Shift Lights

I have a shift light and it needs a signal either the neg of the coil or the tacho signal off the ECU ( which is pin 2, I belive) I am not sure which colour is the neg on the coil ? But what is the best source for the signal?
Kind regards

I took mine off the back of the clocks loom, its the same wire you use for the mph convertor. I can't remember the wire colour but will look tomorrow.
I would of though either way you wired it in wouldn't matter?

Your a star thanks, I will do it on the weekend then in daylight and I'm in a better mood..lol
Looks like pin 2 the Tacho signal (Blue with black trace) ?
Cheers

PS

cant remember pin number phil but i took mine from ecu, think you are correct though.
but as stu said it doesnt matter where you take it from really as long as its the signal wire

Cheers, if any of you do find the wire colour just let me know.
Kind Regards

This isnt for the gtir but might give you peace of mind.

Many thanks, will get on with it on the weekend.

All working like a dream, I tapped in just after the ECU the cables were twisted when they fitted the ECU so I turned it around to get more lose wire and joined on about 25mm back.
Thanks again for all the help and advice.
