i cant seem to find a wiring schematic for the 2012 gt...i am about to hook up my nitrous kit and was wondering where to pull the RPM signal for the RPM switch and which wire from the throttle body to use for the WOT switch...thank you
I think i pulled from the front pass. Side coil for my shift light
Use the brown wire to read WOT correctly. If you use the green/violet wire you will activate the juice at half throttle if you have met any rpm requirements that you set. You may already know but just make sure you set the voltage by opening the throttle blade and not by using the gas pedal. I kept getting a false reading when I opened the blade 100% and it would not activate at all. So I found where I felt 95+% was and set it there. After work I will go look and see which wire I got the tach signal from, don't remember off hand. I believe it is the common color wire.
Didn't have time today to remove the strut bar and engine cover to check mine as I have some things I need to do but here are the instructions I used when I did mine
Raptor Performance-Shift Light Install Info-Mustang 2011 5.0L/5.4L
First part tells you exactly which wire.
Hope that helps
