GMPP E67 PCM Reverse Lockout Wiring

[130fe]

Yeah, that sounds right. I did it in my GMPP PCM. You have to remove the plug (in the particular pin location in the connector) and add a pin to that connector. Connect the other wire (on the RLO plug) to an IGN source. The PCM sends a ground signal to activate the circuit. I didn't enable it in the tune though, works fine. What trans are you running? If you have anything but a 40 tooth trans, you WILL have to reprogram it in the tune for everything to work correctly. I can tell you what to do in that aspect (what setting you have to change).
