TPS and Tach wire on 99 SS
TPS and Tach wire on 99 SS Anyone have a schematic for a 99 LS1??? I need to find what PCM wire I can hook into for the tach signal and also which wire is it on the side of the throttle body that I hook into for the TPS.....trying to finish up my wiring on the car tonight and the window switch is all that is left.
thanks in advance!!!

Tach Signal – Pin 10 on the Red connector ( White Wire )
A better place to pull tach instead of going off the PCM is to go off the main coil pack plug on the female side ( its a white plug the all the coil wires go into ) on the passenger side. There will be two row's of wires. You will need the top row ( Row closest to you ) and it will be the second wire from the back ( or second wire from the left ). IT should be a solid green wire or a light green wire w/ a white tracer.
The TPS can be pulled from the Blue wire coming off the TPS Sensor.
