The whole 80 pin connector assy ? Ebay. Junkyard. The connector bodies are the same between the red,blue,green types. You can use a pick to remove the coloured shrouds from the body and swap them etc.

They are NOT the same. Red and green changes. Can be modified to work.

The removable transparent coloured pieces have the keying ribs on them. They are technically known as "TPA". Part numbers 12176410 12176408 The main metal/plastic housing does not have keys and are interchangeable.

OP, you can get those from mouser.com if you don't want to go junkyard diving.

?

When my 06 PCM fried, I bench-flashed a 2000 PCM, popped off the green plastic covers from my 06 harness and clipped on red ones. Plugged it into the older PCM and it fired right up.

The plastic determines what harness it plugs into, the pcm case is the same. I flash 98-2007 pcms all on the same bench harness.

Because you only need the blue plugged in to bench flash. Red and green are keyed different.

I know a source that sells them but they are not a sponsor so it would probably get deleted if I post it.

sorry for the confusion, the BODY is the same, the colored "clips" that go on the pins DO change. The keyway changes, but you can get a knife and "modify" it to work is what i meant. In the case of a green to red or red to green. For a bench harness, you only need the blue connected, and 99-07 they all have blue so no need to change that. As 2xls1 stated above me

They r "Delphi 80 cavity Micro-Pack 100w". They r for the Ls1b pcm. You can buy the red, blue, or green "TPA's" from EFI Connection, Mouser, Waytek, ebay, junkyard.

So you can plug a V6 pcm into the blue connector, download a V8 OS, and then I will work as a V8 ECM? I'm confused here. LOL

When you plug HPT into an F-body PCM, it will say 4.3 V6 / V8 on it.
