So I delivered a new wiring harness to my mechanic for my 1988 300Zx he says it wont fit! The parts guy swears he has sold a dozen or more with none coming back! Is there a trick, or what? How do you get these wired in?

Impossible for use to figure this one out without knowing the part number of the harness.

The part supplier only list them as being Fuel injector Plug harness 84- 89 (6) NOS I don't know engines at all! I bought this car 4 years ago when my daughter turned 16, she didn't want it so I started driving her and fell in love! However I haven't been able to pin point the nature of her driving so ruff. I recently had her inspected and all they could find was corrosion on the wiring harness! Any help appreciated!

Strange that it won't fit. Can your mechanic source the proper harness? I looked on Autozone.com and they sell each injector plug individually and it must then be wired in. Here is a link on what I'm talking about...http://www.autozone.com/autozone/parts/GP-Sorensen-Fuel-Injector-Wiring-Connector/1988-Nissan-Datsun-300ZX/_/N-ihug5Z8vee1?itemIdentifier=429330_414003_18525_ Maybe your mechanic can only replace the plug that is corroded? I'm assuming you can have your mechanic diagnose what your real issue is with the car running bad, be it that it is injectors or plugs, filters, etc.

dont waste your time on a harness if its not really too shabby.look to normal reasons for running bad,then see if needed,start with plugs,fuel cleaner,correct line pressure ,and air flow ,and clean mass flow sensor with a non harsh chemical like window cleaner,timing if can do also it all adds up,assuming this car was never molested by a tinker do it myself owner without any knowledge ,just rip and tear

1988 z uses an offset nipple. The earlier 300zxs used an injector plug that has a nipple centered. That is most likely the issue you are running into.
