PCM side connectors for red/blue OK so to be clear up front, I am NOT looking for the red/blue GM harness connectors that plug into the GM PCM.
I also searched and have not been able to find an answer yet.
Long story short, I need to make an adapter harness for a PCM swap to convert a GM PCM harness to an aftermarket ECU (namely a MaxxECU Race). The car currently has a well-integrated and operating PSI Conversions swap harness that I DO NOT want to remove. So, I want to make a custom harness that emulates the connections on the GM PCM so I can plug the PSI harness into the MaxxECU. The current harness is for a 2002 red/blue GM PCM.
MaxxECU makes a generic pigtail harness (as one would expect) so all I need is the GM PCM side of the equation. Again, what I need is the pins/shells for the PCM SIDE and NOT the harness side. Short of gutting a junkyard PCM for the case/backshell and the pins, I have not found anything.
Does anyone know where to get the GM PCM side connectors?
I know I can depin and rewire the PSI Conversion harness but I would rather keep the red-blue connectors in place and make a PNP adapter harness.
Thanks

That's because that doesn't exist. I know what you are trying to do so the easiest way would be to make something out a PCM, use the face of it as an interface and wire the pins on the other side in it for what you need to that MaxxECU. You'll have to hard mount it so I would mount it in the stock location and then use the space behind it to mount the other system.
I do electronics for work and have done similar for things, it's possible.
