Wire Harness

Will the wire harness from a 87 305 TPI work with a 89 350 TPI?

Re: Wire Harness

Are they both Speed Density or is one MAF?

Here's a valuable link to help answer your TPI questions.

BTW it's a MAF system and the harness should work but do your homework to be sure for yourself.

Good luck

Re: Wire Harness

Your 87 has a ninth injector, but your 89 doesn't no biggie I guess. I would get a custom PROM to incorporate cold start characteristics.

Are you doing an 89 engine swap into an 87 car?
