Hello everyone , would anyone might know where the trailer witeing harness connects too? The one that GM provides. I see no directions for its installation. As seen in the picture . Planing to add the etrailer max frame class 3 ( 2 inch hitch ) to it so I can add maybe a basket and or a bbq pit to it , to make for some better beach trips, fishing trips / more cargo for road trips .
But I would wanna add that third brake light so people can see where it ends just in case .
2 links will be provided . One for the wiring harness and the other for the hitch.
The hitch I can do but where would the trailer harnesss go. It seems plug and play.
I wouldn’t wanna have to mess with the wiring system just to have brake lights .

I also trust etrailering because a friend got a hitch and bike rack from them for his Subaru BRZ . So yea .
Any info please and thank you, I’m sure this will help others.
