I am going to install a AVCr on my car this weekend but I need help finding what wires to tap into from the ECU. I need to tap into the follwing wires: speed, RPM, throttle, the ground and the power wires. Does anyone know the ECU wire numbers/ color of the wires for these? The car is a 2001.5 A4 I searched and all I can find info on is wiring for a S4.

any help will be greatly apreciated

Thanks
