Here's a bench harness I came up with to be able to access a gpec2a pcm without having it installed in a vehicle.

My junkyard spare came with the connectors attached, so I stripped down the appropriate connector leaving just the wires needed for the harness. I had to get an OBD2 connector from Amazon, but already had everything else, including the connector needed to use my NOCO 10 as the power supply.

Here's a diagram of what I came up with.

Here's what it looked like assembled without the switches or voltmeter attached.

Here it is powered by the NOCO 10, connected to the pcm and a vLinker MC+ OBD BT adapter.

And here's the result of a successful read of the unlicensed pcm from jscan.

This gets me excited. Nice work! Want to build another and then build one for the GPEC5 and send it to me? 😂 Some of these companies want $200+ for adapters which is nuts to me. But I’m looking into bench flashing tuning as an option.
