It seems that the fuel pump control module (FPCM) has an 8 wire plug. Power comes in from the fuse box via pin 1 and grounded at pin 4. Pins 3 and 7 go to the PCM - probably power to the module and ground, I'm guessing. Pins 5 and 8 are the output power and ground. Pin 6 is restraints control.



I've installed the 2014 5.0l engine in my early Mustang, but due to the 6R80 transmission, I'm trying to use a factory wiring harness. I tried to bypass the FPCM...
