I was wondering if anyone can help me figure out a pinout diagram for the wiring harness on my "07" mustang GT body wiring harness plug that connects on the passenger front corner in the engine bay.
For contexts I bought a 06 GT auto car and a 07 GT manual car, I swapped the manual trans, dash, steering column, computers and all wiring harnesses but the one harness I forgot to swap which is different is the body wiring harness that starts in the passenger front and runs down the fender.
issues I'm facing currently are the car doesn't fire up from the key but I can start it with a jump switch and a hot wire to the fuel pump.
keeps throwing codes for throttle position and forced idle even tho both the sensor and actuator are working and I have throttle response
My first assumption is that has to possibly due to the harness I didn't swap but this project has been a huge learning curve for me so thank you for any info in advanced.
I'm going to include progression pics of the build and the plugs I'm needing to figure out, the plug with the outer red wires is the engine side of the harness, and the plug without is the body side.
