Hi All, I've done a few searches but, either I'm not hitting the right keywords or the answer is right in front of me and I am missing it. I've got a TPI harness that I picked up at a swap meet mid 90's maybe. At the time I had a '82 crossfire z with a modified 350 that was carbed. I was intending to do a TPI swap. Never happened. Sold the car at some point and moved on. I've been going through the parts I had accumulated over the years for different projects and stumbled upon the harness. Didn't think I still had it around. I'd like some help identifying the harness so I can accurately list what it is to put it up for sale. I'd like to see someone else put it to use. It appears to be a new harness that was never installed in a car. The main connector and a few others have bags over them. I can see a silver writing on the injector connectors (1-8). It has some tape wrapped around it with what may be part numbers but, Google isn't being my friend, so I haven't had any luck. Here's the numbers: White Tape: 3626 Orange Tape: 14 Label 12083626 F (maybe E?) 5554 4 90(typed vertically 0 over 9)269 PED 48541 Any help is greatly appreciated. Chris If pictures help, I can try to take some tomorrow or Friday.

Well i dont know about anything with the numbers but heres how i would figure out what youve got:

1. How many injector connectors are there? All TPIs had the 8 injectors but only the 85-88s had provisions for the 9th cold start injector.

2. MAF or MAP connection? MAF covers 85-89 MAP covers 90-92.

3. Connector for MAFS module? 85 only.

Between these facts you should be able to figure out which one you have. the 85, the 86-88, the 89, or the 90-92. I believe that covers ever variation of the harness.

Also, if you can make out what side of the engine the A/C compressor is wired for, that might help. From 85 to 87, TPI used v-belts, and had the A/C on the driver side. From 88-92, a serpentine setup was used, and moved the A/C to the passenger side.
