ok doin a 4cyl to 5.0 swap. car is a 93 and ecu harness is out of a 91. everything is all plugged in and ready to go but go to turn key no fuel pump and no starter? do i need a harness out of a 93 because it has the fuel pump relay in it or can i use the 91 harness and put in a fuel pump relay harness under the seat? need some help quick so anything would be great. thanks
