Thread: Easy bench harness 99+ and 04+

My junkyard build bench harness.
Blue Pcm connector from an ecotec grand am
Blue pcm connector from 3800/ls car.
Obd2 port.




Using this guide it was just sodering and connecting the correct wires.

thanks, i just re wired my 04 up off board, now i need a 04 up pcm to test it on lol

Wanna post a write up of exactly what pins to what pins for the 04+ ?

E40 (Gen-IV V8) and LLY Diesel Controllers copy this one.


controller to the obd2

Exactly what i did. I wired mine for can (+/-) and class 2. That way it should do any controller with the 04+connection.

Here's mine. With red switch for power and green switch for "ignition". Worked perfect, powered off a hacked PS3 power supply and successfully wrote my first BIN offline with DHP.
