eDIS wiring tacho help please read

[Phil 99]

Hi

Need a bit of help. Got a mk1 phase 3 and wanting to put the RT/16v instrument panel in, with tacho etc. Ive put up a post similar to this before, but im DETERMINED to get this in and working myself, but i just need a bit of help (from one of u kind people) .

Anyway i understand in the phase1+2s its a straight swap and it all works, but the ph3 has a different engine. And i dont have any idea where to wire the tacho to. Someone said about an "electronic distribution module (eDIS). Does it wire to this, where is it in the bay, and how to u do it? All i really need is a pic of the engine with a few arrows as to what goes where and im sorted (if its that simple?). An auto electrician should know what to do

Any help really appreciated

cheers, Phil

You need to have the Tacho converted in the dials to work with an eDIS.. costing roughly £75. Company called Speedy Cables did mine.

You then wire it into the eDIS module. You need to run a cable from the engine bay to behind the dials.. this cable is then cut into a wire going into the DIS module and soldered on.. it then connects to a new wire for the Tacho.. which was installed by Speedy Cables.

You then have to fine tune the tacho so it reads correctly.. there is a small potentiometer on the back of the new rev counter, which you can turn and it adjusts.. I let my car idle then set it to 750.. which is what my car idles at.

Now, I did it.. and I dont reckon it was too hard.. cutting into wires to the ignition module, tho, is pretty scary. If you aint 100% sure, Id get an auto electrician to do it..

Thats how I got mine going anyway!

And ok, it cost £100 (dials and tacho conversion), but it is worth it - the Oil level dont work.. but that dont matter (it only should work on Ignition anyway).. but the Temperature works which is useful too.. Im glad I did it.. use the rev counter loads.

Check out a Haynes manual..

I do advise heavily against doing it if you aint 100% sure.. if something goes bang, Im guessing it wont be cheap..

You contacted any Auto Electricians? I rung round a few places and one wa svery helpful and spoke to me over the phone about it.
