Any of you guys out there that have installed a PCS in a former Powerstroke truck please help. I'd like to know what color wire and where you located them on the factory Ford harness to hook all of the inputs to (RPM, Speed Sensor, MAP, etc). Any and all help is appreciated! Confused

You can find all the info you want on powerstrokes at www.thedieselstop.com

Behind the instrument cluster, white/pink is rpm, grey/black is vss (output to ecu), coolant is yellow something, can't remember exactly - just look at the back of the cluster, the signal wires are labeled on the breadboard and you can trace them back to the right wire. I have a PCS controller in my powerstroke, works great.

Do you have your calibration file? I hooked my pcs up with the wiring you suggested and I must not have something set up correctly. My tach pickup reads backwards (goes down when engine rpm go up) and I am not getting any input from the speedo. Thanks for the help!
