If it’s for a camera get power at the brake light and ignition on power for the monitor.

you can tap into the reverse light for 12v+ OR from the hitch power supply..
I suggest a 3157 splitter cable and tap into the 3157 splitter cable AS not to damage your SUV wires


this way you don't have to run a very long cable

Depending on model, ls, lt, ltz or even pickups.....label 1 is usually occupied as is 3 on suvs but label 2 is where gm allows ‘upfitters’ an easy way to plug in their accessories. The labels in first pic are for cavity 2 in 2nd pic which has constant, ground accessory and even rap.

Ok @Galante my man I am having issues here. I am hooking the IGN and GRND pins to run my dash cam. And I am pinning ACCY to feed the signal to my sub amp. The sub works fine, comes on and off with accy like the HU does. Perfect. BUT, my dash cam is not firing up. I am getting a hot test light on the IGN pin. To me that says the GRND pin is no good? BUT, when I was installing the connector on the GRND pin (It's like playing that ******* "Operation" game) I bumped the pin below it, whatever that is for, and it sparked. And now the bottom pin is not hot anymore. I have no idea what that pin is for or where the fuse is for it. Not that I need it for anything, just saying it was a casualty and I don't know what may or not be affected by it. BUT that must mean the ground pin IS good????? Do you follow me? Halp? Maybe it is not enough amperage to power the dash cam? It must, the wires in the power cord are **** hair size...
