Wiring Reverse Light Circuit to 7 Way Connector on 2016 GMC Terrain

Question:

I am installing a 7 pin connector to my 2016 GMC Terrain. Which wire on the vehicle do I connect the reverse light pin to? Also Can I connect the Aux Power pin to the rear 12 outlet rather than making additional run to the battery?

The center pin of a 7-way is typically the reverse light circuit. You'd need to tap into the reverse light circuit of your 2016 GMC Terrain to activate it.

For a quick splice for 14-18 gauge wire you'd want # SWC501746-1 or for 10-12 gauge wire # SWC501915-1.

I'd recommend strongly that you run the 12 volt power wire back to the positive post of the battery and not to a 12 volt outlet to prevent shorting out that circuit.
