On your harness you should see 3 grey wires. One has a red stripe, one has a blue stripe, and one has a black stripe.

Grey/blue goes to your leading coil, and to the pink or green/yellow wire(depends on which side of the connector you look.

Grey/red and grey/black go to the trailing coil. Grey/red goes to the blue/yellow or pink wire(again depends on side of connector you look). Grey/black goes to the brown/yellow or white wire(again depends on side of connector you look).

Hope that is what you are looking for. All this info can be found in the manual which you can download for free from the Microtech website.

i thinks that how i have it wired but i know the the grey,red or grey/black both i know niether one is hooked up to the yellow/ blue wire.

Ok.
Its very simple.
to get the tachometer working(assuming the car is running well) it has nothing to do with the microtech to get the tachometer running(dont know why it stopped really).

On the trailing coil paks(big ones closer to the firewall) on the coil pack side of the plug their is a yellow wire(look well sometimes the color fades abit and they are dirty). this is your tacho OUTPUT signal. This goes to your dash.

thanks both off you guy i got it i just hooked the grey/red wire to the yellow/blue and it satring wokring. dang i didnt know i was ideling that low 900 rpm
