I´m intalling a turbo timer and I need to know which wire that comes from the ECU is the speed signal wire.

anybody knows where can I find out wich wire is it?

I don´t want to be cuting wires testing wich one is it.

thanks

Pick up a haynes manual, you may be able to find it in the wiring diagrams. What are you installing a turbo timer for anyways? You boosted?

where can I find this haynes manual on the net? and yes I´m in process of boosting the car
