I swapped the EFI off of an '89 runner in my '84. I used the complete wiring harness and EFI system from the '89 and everything went back together perfectly. I didn't have to cut or splice any wiring. This should work on any '84 to '88 truck or '89 runner as long as they are the same body style.
Thanks bluetoy I am getting a Efi from a newer truck to get a little more power . Lynn
