Review on ✅ Gm 2014-Up Backup Retention Harness by AXXESS: Ensure Seamless Backup Integration with Your Vehicle! by Adam Aponte

I had a factory WT radio and upgraded to an Android Auto radio. I did a little digging, but I finally found a post showing that the camera + is connected to the X1 connector on pin 5 and the camera - is connected to pin 4. I used Metra LC-GMRC-LAN-09 AXXESS GMRC-LAN Interface GM Connect most radio functions. Remove the pins from the wire harness on this part (backup cam wire harness) and insert them into the new connector that goes into the X1 wire harness from the radio. Note that pins 4 and 5 are on the original factory connector. Count the pins starting with the top row and move from left to right on the original radio connector. I wish I could explain it better, but it's not as bad as it sounds. The weird thing is that there is a connector in the interface harness that detects when the truck is backing up, so you don't have to worry about that if you're using the interface I'm using.
