Hello guys, I'm currently in a pickle situation. I bought a 2003 Mustang Mach1 but it's not complete. So far i have the shell of the car with suspension, wheels, engine and transmission. A friend suggested to buy a 2003 Mustang GT as a donor car in order to use the parts from the 2003 GT in order to finish the 2003 Mach1. I know they are mostly the same car but I'm wondering if wiring would be the same? I appreciate any feedback and help you guys can give. I want to finish this car as soon...

2003 GT to finish my 2003 Mustang Mach1?
