I have a question about the pats system on a motor swap. i have the motor/tranny/computer out of a 03 mach 1. I am looking at putting it into a 94-98 stang. if i get a stang w/o pats will i have problems because of the mach 1 computer?
Just use the GT harness and computer. You will have to modify the GT harness for the 4v cops, but it's easy. You will have to modify the alternator plug and lengthen the coolant temp sensor plug. Possibly some other minor differances. But overall it's pretty striaght forward and simple. Helps if you know how to solder and heatshrink wires. Do not use butt connectors!
LMK through pm if you need any help or have any questions.
