Hey dude,

You only have to do it if you want the Mk5 dials.

Mk4 dials fitting info is still here: http://fiftyonecl.hopto.org/st2000/ff3latespecinteriorguide.html ('cor, long url! ).

ah so me being a little bit new on the whole mk4/5dash, whats the difference?

Well, this is a guide to fitting dash clocks for a start...?

The Mk4 dials use a mechanical speedo but are easier to plumb in.

ah yeah sorry thats what i meant cheers.

You know that you are a very kind chap for doing these guides

I will be attempting this on my mk4 later this evening... one question, how would i change the amount of miles on the digi clock as the dials i have came from a much younger car.

*This is a purely hypothetical question and in no way suggests that either I or project would tamper with the said items

[peewee]

Hey, i have attempted this mod on my fiesta... I have got the speedo and tachometer working. The fuel gauge is working... but backwards as u said it would... did you change the whole fuel tank to fix this problem, or is there another way to get the correct signal.

Also, i can't get the coolant temperature gauge to work using the same signal as my old gauge.

do i need to change the temp sensor? or will this then give a different temp reading to my ecu?

I am asking all of this because some of the stuff on the site isn't working. i.e. the pics and links to the wiring.

[John_D]

hi m8,ive got a mk6 set of clocks im hoping to fit this weekend, any chance you could put the pic's back on your web site

[Gazeddy]

can the clocks be swapped out like on the mk3 so i could say take the digital speedo from mk5 and put in mk4 set

[John_D]

do u have this up anywhere else m8 as its no longer on the site.

Mk 4 dials in mk 3

What's this then?
Bored of the Mk3 dials in your Fiesta? The Mk4 dials can be fitted very easily and work fine with the Mk3 sensors, and the sports models came with white faces and red/orange needles, which look a whole load better than the clunky Mk3 dials.

What's needed?
For this conversion you will need the Mk4 (mechanical speedo) clocks, and the two multiplugs with a couple of inches of wire from the back of the Mk4 clocks. You'll also need a soldering iron, solder, heatshrink, a few metres of 5A wire, spirawrap and/or electrical tape, and a few hours spare.

How to...
Work through the table below, connecting up the Mk4 multiplugs to the Mk3 wiring loom. It's probably a good idea not to cut off the Mk3 dials multiplug in case you want to switch back to the old dials, and it's also probably a good idea to extend the Mk4 wiring by a foot or so to give you some extra room - you can always tuck it out of the way once it's all working!

This table lists the wire connections you need to make for the Mk4 clocks on the Mk3 loom:
Mk4 Pin* Mk4 wire colour Function Mk3 Pin Mk3 wire colour Function (same as Mk5 unless stated)
A1 Violet +12v 6 Black/yellow N/a
A2 Black/red Low fuel warning light N/a N/a N/a
A3 Black/orange Low washer fluid warning N/a N/a N/a
A4 White/green Glow plug warn light N/a N/a N/a
A5 Black Earth 13 Brown N/a
A6 White/red Fuel gauge 5 Brown/black N/a
A7 White/red Engine temp gauge 4 Brown/white N/a
A8 Black/blue Brake system warn light 11 Brown/yellow N/a
A9 Black/red ABS warning light N/a N/a N/a
A10 Black Earth 13 Brown N/a
A11 Violet/white High beam 3 Blue/white N/a
A12 Orange/blue Dash lights 14 Grey/yellow N/a
B1 Blue/black Indicator, LH 1 Black/green N/a
B2 Blue/yellow Indicator, RH 2 Black/white N/a
B3 Black/blue Door ajar warn light N/a N/a N/a
B4 Black/red Traction control warn N/a N/a N/a

B8 White/black Rev counter 12 Green N/a
B9 Black Earth 13 Brown N/a
B10 Black/green Low oil pressure warning 8 Brown/green N/a
* A denotes the connector with 12 contacts or pins. B denotes the connector with 10 pins.

Notes:
• To wire in the door-ajar light, connect pin B3 (black/blue) to the brown/red which runs down the A-pillar from the courtesy light.
• The pin numbers on both Mk3 and Mk4 clocks seem to be a bit random (thanks Mr Haynes) and may not match up to the actual pin numbers, but tracing which connection is which is easy enough.
• One problem you might come across, depending on the loom type in your car, is that the rev-counter may read half (usually HCS and injected CVH engines). If this is the case, you will need to locate a wire in the loom (usually green with a trace or plain green) which pulses on both coil triggers. On injection loom, this is usually one of the green-coded wires passing from the ECU to the E-DIS module.
• Mk4 dials aren't normally lit in red or backlit - they come with green front lighting, but it's very easy to change the colour of the dials and I'll do a guide on this one day... maybe!

Mk 5 dials in a mk 3

Right kids, listen up - this is my rough guide to fitting Mk5 digital dials into your Mk3 Fiesta.

The guide doesn't cover the actual fitting of the dials into the Mk3 dash - if you're doing that, you can either fit the dials through the back of the dash (i.e. you have to take the dash off) or (more easily) by trimming the bottom of the dials hole in the dash as the locating lugs on the bottom of the Mk4/5 dials foul the mounting tabs on the dash.

First up, you're going to need:
• a set of Mk5 dials. Any ones should do, but the white-faced sport versions are the most popular. Some of the low-end ones (including diesels) don't have rev-counters. They still look good, but there's no real point fitting them, is there...?!
• a metre or so of spirawrap. The best stuff to work with is the smallest version Maplins do (it's about 2mm wide and has a 1mm hole, but you can stretch this out to cover looms up to about 10mm diameter).
• soldering iron
• a metre or two of solder. Use silver solder if you can - it gives a much cleaner joint.
• a box cutting knife to remove insluating tape
• a roll of insulating tape (get the 99p for 5 metres rolls from Maplins, but the £1.50 for 1 metre rolls from Halfraud's)
• screwdrivers
• wire stripper/crimping tool
• ring crimp terminals (about 10mm outside diameter) and a male and a female bullet or spade crimp terminal.
• fluffy toy
• assistant to provide endless mugs of tea
• a reel of equipment wire - Maplins do ~15A wire on a 100m reel for around a tenner, which is excellent value and you'll soon use it on other car jobs (if you don't, send it to me - I can always use it!). You can also buy it by the metre if you want - it's about 35p a metre I think.
• lighter or a heat gun to shrink your heatshrink (don't use your soldering iron - you'll scorch it... ouch)
(All the images are clicky, by the way).
You'll also need to work out what all the wires do. I've got a guide here, but I *think* the indicators need to be swapped, and the warning light circuitry needs to be earthed. When I re-do the wiring I will confirm all of this!

The other big problem... - the fuel gauge reads backwards on digital dials. All of them as far as I can tell. You've got two options on this - one is to fit the Mk5 tank sender, and maybe the tank as well depending on whether or not the sender fits the Mk3 tank - or grab yourself a 741IC (small chip, about 30p from Maplin) and a book on 741 circuits to invert the signal. I think swapping the tank will be easier for me, but it's your call!
Next job is to strip the wires back on the multiplug loom but don't solder them just yet. One mistake in this pic - the earths (black) are zapped together. Because of the electronic circuitry, the earths need to be "clean feed" as much as possible back to the chassis - you should extend each individual earth back down to the earth point on the steering column, so add about 2 foot of good (20A) wire to each connection, and crimp (then solder) on a ring terminal to give a good connection. If you cheat like I've done here, then you'll end up with a rev counter that bobs up and down just after starting the car when the battery is slightly low on power, and other weird happenings!

Hokay, next up - remove the dash surround and your old dials. There's a pic here somewhere but it's of my Mk4 dash so it's not really much help. One tip - the speedo cable comes out of the clocks by pushing across on one side of the large plastic ring next to the back of the dials. It doesn't need to be yanked or pulled - when you get it right, it just slides out. Easy money
In this pic I've started removing the spirawrap from my clocks loom - you'll need to cut the insulation tape off your loom. Best thing for this is a box cutting knife with an adjustable blade. Have the knife set so you've only got a mm or two of blade showing, and be careful to run the knife along the wiring, not through it!

You should keep your Mk3 dials plug on the loom for this conversion, so you can swap back to the Mk3 dials if you need to test your wiring, or if something won't work properly. Easy enough to do this: starting with the first wire on your list (which you downloaded and printed off earlier from my site, or worked out from the wiring diags, didn't you? ), make a cut in the Mk3 loom about 4 inches from the multiplug (to allow you some room to manoeuvre) and strip the ends of the wires. If you don't have enough length on the Mk5 loom (you should have a good 6 inches to play with... stop sniggering at the back), extend the wiring with some of your equipment wire. You did buy some, didn't you?
Twist together the bared ends of the wires running to the Mk3 and the Mk5 multiplug, and solder them, then do the same to the remaining wire:

Then put an inch or so of heatshrink over the single wire and push it a few inches up the loom (so it doesn't shrink with the heat of soldering)...

... and solder the wires together:

Then slide your heatshrink over the joint and heat it until it shrinks down nice and tight - the tighter it is, the better. If you haven't used this stuff before, be careful not to overheat one side as you can burn it:

The loom I had was from a boggo fiesta with no rev-counter wire at the multiplug, but it did have a couple of spare pins (listed in the guide I made up) - for example, the traction control light, so I used the multimeter (£4.99 from Maplins... God, I need to get a life) to identify a spare pin:

That loom again: pick a wire...

Using a couple of fine screwdrivers or a fine blade (watchmaker's screwdrivers are handy for this), press in the retaining tags on the side of the Mk5 loom, and slide the pin holder out (don't worry, the wires won't all fall out):

Grab the screwdriver or blade again, and press in the retaining tag on the pin you've chosen to use, and pull gently on the wire at the same time to withdraw the wire:

Once the pin is out...

... push it into the rev counter pin hole until the tag engages. If it won't clip it, pull it out (gently) and bend the metal tag out slightly with a fine blade.

If you want the door open warning light to work, you need to tap into the courtesy light loom. I've gone in through the right-hand air vent here...

... but you should drop the car's main loom down from under the steering column and tap into it there if you can. You're looking for a brown wire with a red trace - the easiest way to get to it is to remove the insulation from the loom, find where the wire goes into the door-pin switch and trace the wire back to a suitable location in the loom (e.g. close to where the loom passes under the steering column).
Remove the insulation:

... and strip back the insulation (you should cut the wire if you have enough slack - I didn't have any slack here, and shortening the loom would have made it more likely to break under the strain). Wrap the wire from the door open warning light (which you will need to extend along the existing loom - try to avoid running wires straight across the back of the dash as it makes the loom very messy and hard to manage) around the bared brown/red wire, and tin it:

... then wrap in insulation tape, and tape the loom back up:

Messy... sorry!
Your clocks are going to need a permanent live feed (so it remembers its odometer info) and an accessory (radio) feed (I think...!?). I've taken a feed straight off the ignition loom but remember the ignition loom is unfused and can take around 100A current before it melts. You clock wiring will catch fire much sooner, so add a fuse as close to the joint as possible!

Use your crimp/strip tool to pull the insulation back on the wires you need to tap into (little tip: make two breaks in the insulation about 5mm apart, then use your box knife to cut aliong the 5mm of insluation and peel it off):

Then, like you did with the door warning light, wrap your feed wires around the supply wire (uhhm, you should have disconnected the battery, but just in case you didn't, like me, be careful not to let the wires touch earth or it gets a bit noisy...) and solder, then insulate properly. Again, run the wires along the existing car loom.
Use heatshrink to tape back the old wires:

(Don't cut the wires off - they're handy if you want to add other warning lights to your car, and if you break a pin!).
Right, next up - speedo wiring. Find your speed sensor (injected models only - not got one? Get one from a scrappy's. It needs an ignition live and an earth). Here's the multiplug we're looking for, just to the o/s of the brake servo:

Welcome to my bulkhead. Yours will look a bit like this, but not *quite* the same... You'll be running your speedo wire along here (as well as a rev counter feed if you didn't have one, but I'm not covering that in this guide):

Unscrew the 10mm retaining bolt and lift your header tank out of the way. Undo and remove the insulation tape from one of the rubber nipples on the cable grommer behind the header tank, and pass a feed wire from the clocks through here and along to where your speedo sensor plugs in:

I'm going to say it, but I don't believe for a second you'll do it... you *should* strip the insulation off the car loom all the way along to the centre of the bulkhead, and tape the speedo signal wire in, but if you can't be arsed to do that, at least tuck the wire out of sight
I found that my speedo sensor had dropped a pin, so my car wasn't getting a speed signal to the ECU - not good really. Get the speedo sensor off if you can, so you can give it a clean up. Connect your signal wire to the yellow/black on the speedo sensor-side of the speedo sensor multiplug and add a blade/bullet connection in-line so you can disconnect the wiring if you drop the engine out:

Here's the state of the dash wiring loom:

The speedo cable's tucked out of the way, and the loom needs a hella tidy!
That's better:

Once you're done, plug in and test, take it for a drive, then if you're happy it all works, screw everything up and admire your work!

One nice little trick with these dials: hold the trip button down as you turn the ignition on (it'll reset your odometer though) and you can access the test/data function of the clocks (ignition off and back on to exit). More info here: http://www.fiestaturbo.com/phpBB/viewtopic.php?t=85135

Wiring in the Mk5 clocks

If you are fitting these clocks in a Mk3 dash, you will need to fabricate 4 small brackets to correctly align the 4 screws which hole the clocks in place. The clocks are the same shape as the Mk3 ones they replace.

For this conversion you will need the Mk5 (electronic) clocks, a speed sensor from a Mk5 Fiesta or other late Ford, and the multiplug with a few inches of wire from the back of the clocks. The Mk5 speed sensor replaces the speedo cable at the gearbox end. You can mount this on top of your existing speed sensor if your car is ECU-controlled.

This table lists the wire connections you need to make for the Mk5 clocks on the Mk3 loom.

Note that, like the Mk4 pin numbers, the pin numbers on both Mk3 and Mk5 clocks seem to be a bit random and may not match up to the actual pin numbers, but tracing which connection is which is easy enough.

One problem you may encounter, depending on the loom type in your car, is that the rev-counter may read half (usually HCS and injected CVH engines). If this is the case, you will need to locate a wire in the loom (usually green with a trace or plain green) which pulses on both coil triggers. On injection loom, this is usually one of the green-coded wires passing from the ECU to the E-DIS module.
