So a little back story (without going into too many details): I purchased this car (1977 280z bone stock and sitting in a barn) extremely cheap ($900), everything was there and seemed to be in place; however, the previous owner said the car needed a new AFM. I purchased the car and AFM and installed it. The car ran, idled, etc.
While going through the entire car, I found that the engine bay wiring harness (fuel injector clips, other 2 prong clips, and wires looked like they had seen some sort of heat as they were all fringed and brittle. I was able to source a completely new harness from the ECU forward; however, it came out of a '78. Everything will match up except for the AFM connector. My '77 has 7 pins where the new harness from the '78 has only 5 pins. This is because Datsun changed from having the fuel cut-off controlled by the AFM to having it integrated to the oil pressure switch/sending unit (feel free to correct me if I'm wrong, but i'm fairly close with that statement, i think lol).
My question is this: Can I still use the '78 engine harness on my '77 and if so, how do i bypass or "jump" the fuel cut-off pins/switches within my '77 AFM? I have heard bits and pieces out there that this can be done but after hours of searching, was empty handed.
I'm extremely excited to get my hands dirty and get this Z on the road as it's my first 280z.
Any help will be greatly appreciated.
Thank you in advance.
