Ok so I'm trying to figure out if the body harness, key ignition w/ key, gas pedal, dash harness, and everything connected to it Will it plug right up to an engine and harness from a different donor 350Z?
I have a VQ35de engine and engine harness and missing everything else. If I get the rest of the stuff from a different donor car (the same car), will it plug right and and run correctly without having to take it to get it reprogrammed at Nissan cause I don't know anyone there? I want to run the stock electronics. Pretty much do a complete changeover minus AC/PS. I really want to do this swap, but this is the only thing holding me back from doing it. I don't want to buy all the stuff and it won't work.
What I think is that the engine and engine harness shouldn't matter because the engine harness is just connecting the engine to the ecu. Also the sensors on the engine should be the same as every other VQ35de engine because if that sensor goes out then you just replace it, right? Please correct me if I'm wrong. I say this because civics and integras are like that because the engine harnesses are interchangeable if your swapping a v-tec motor with a v-tec motor as long as it's obd1 or obd2 then it should plug right up and work. I do these swaps all the time for people and they pass reff with an ease.
