Is there a difference between a z32 TT 1995 wiring harness and a TT 1993 harness. I realize the injectors are different but what else if anything? ECU socket? Thanks My goal is to purchase a 1995 computer and and use a 1993 harness.

Why would you buy a phase 1 harness? you should get a phase 2 (1994+) TT harness, that way you are up to date on the injectors, CAS, and PTU. All these updates were done for a reason. The ECU end is the same for all OBD1 cars.

^^^^This.
There is no possible gain from what you mention and would take a lot of trouble for no reason, best bet is to replace with what was meant to be there unless there is a solid reason to change something for an upgrade, update, or ease of maintenance.

The reason for switching everything up is I have 1996 computer running a pre-96 TT Engine inside of a 1996 slick top NA 300zx. 1996 is a pain in the a**! I am getting heads and just about everything else that will match a 1995 closely. I have a dual pop intake, getting a 95 ECU tuned by JWT, 615cc NISMO injectors installed, new PTU and a late style CAS. The new heads will have port work and a JWT S! mild 100 cam with Z1 Heavy duty lifters. I wanted a 1995 harness but ran into a good deal on an earlier harness. Thanks for your input!

A new 95 harness from wiring specialties is just over $500, with all the work and money you've put into the car don't cheap out on the harness. Or if you're game you can always order all the 95 connectors from wiring specialties and splice or pin them into your phase 1 harness. Word of advice: if the phase 1 harness you bought isn't new I would buy a new harness become very brittle with age and heat cycling. And replacing an ECU harness with the engine in place is a special kind of PITA.
