i just did a 3.8 to a 5.0 swap in my 95 mustang, i changed the wiring harness ecu, fan control modual. fully rebuilt motor. I got everything hooked up and it wont crank over. I have fuel pump, interior lights, etc. I didnt change the ccrm and it is making a clicking noise. But it always has a tranny from an 88 that had the neutral safety switch it was wired together to try to bypass it.. i need helppp!!!!!!
