2017 Silverado Trailer Brakes

14852 Views 20 Replies 8 Participants Last post by  Larryboy_3t5
I'm planning on towing with my new truck, and it has a 7pin/4pin in the bumper. I was informed when buying the truck, that it was already wired to the dash for a trailer brake controller. So I went out and I bought the OEM AC Delco switch and plate and installed it myself. Here's my problem- The Trailer Gain page isn't in my display. I've been looking left and right trying to figure out anything on my own.

Is this missing software that I need real help on, or does it not show up until a trailer is plugged in? Also, does a 7 pin test plug work on tricking it into thinking trailer brakes are attached?

Any help would be greatly appreciated.

"So for now I'm grabbing an old voyager and hooking it up for this trip. When I get the time to leave my truck at the dealer, I'll have them reflash it and let you know how it works :)"

Ok, I'm old and confuse easily, so let me get this straight. Not sure what kind of load you will be pulling, but you seem hesitant to pull it with a brand new Silverado without a TBC, so you're going to pull it with a Voyager. Are we on the same page here? A Chrysler Voyager, a uni-body, fwd, V-6 at the most pos mommy soccer van? Like I said I confuse easily.
Whew, now that makes sense, Tahoe a good choice, I was worried for a minute, lol.
