i think that you can go two ways, you either take and swao all the engine harnesses from the old engine to the new engine and go from there, I think the only extra thing you would have is a cat monitoring sensor
or you could get all the wiring from the 96, I think you would have to get the in dash stuff also because that would all possible be different and swap it into the 95
so I din't see why you can't swap all the old sensor and wiring over to the "new" engine and it wouldn't work. luckly you didn't have a 98+ engine so you have no VCT to worry about, so I believe the engines are the same
