I am switching my 91 2.3 mustang to a 5.0 I have a pcm from a 89 gt and the harness that comes off the pcm to the outer fire wall. I also have the engine harness for the injectors. What I am having concerns with is the 4cly has a Intergrated module under the hood but I have found under the drive seat a plug and wiring for a fuel pump relay. I was wondering is this wired like the v-8 cars and if so where do they brake the wiring for the intergrated module to relocate the relays?
