Trailer Wiring underdash?

[MR. DRAG SLEDDER]

Hi Guy's,

Lot's of questions here....

1s:- Did your Car come with a Factory Plug? If so where was in located? Couldn't find mine anywhere. I also went to the Dealer and couldn't find one in any of the 17' Acadia's!!!

2nd: Where does it plug in under the Dash? Looked for ever and couldn't find a open spot

3rd: I bought a Plug and Controller from etrailer.com and the one they sent it right but again can't find any spots that looks like the Part #3026 Plug end.

I don't own one, but I'd be glad to help if possible. GM's listed location for the blunt cut wiring is very vague. All I can find anywhere is "In the passenger compartment, forward of the center console." That I guess, points at it being taped up somewhere around that area,

 

Now, from looking at the wiring schematics, the blunt cut wiring is only on Acadias with V92 trailering package. V92 is: Trailering Package includes factory-installed hitch, 4000 lb. towing, 7-pin wiring harness, Class III hitch and (V08) heavy-duty cooling system.

 

Chances are some of the ones you looked at might not have had the factory trailering package?

Thank you 15HDriver!!! I will look over on the side!! I made sure from the window sticker said they had the Towing Package and checked under the bumper cover for a hitch.

Where can I see the wiring schematics??? I am hoping to find with plug and colors the wires are for the Fog Lights and Parking Lights.

Thanks 15HDriver!!! I will look on that side today. Also where can I see the Wiring Schematic for this Car? I want to try finding the Fog Light and Parking Lights for the diode mod. Thanks?

Okay, here is my 1st attempt at a Write Up:

- 2017 GMC Acadia Denali w/V92 (Trailer Pkg. Factory Installed)
- Put the Drivers seat all the way back
- Remove the little square access tab right next to the Gas Pedal
- Use a 7mm Nut Driver to remove the Screw
- Now starting under the Dash start to remove the Center Console side panel. This is held on with clips so it comes off pretty easily.
- Once off of the Console it takes some jockeying to get it out.
- Once out look at the Fire Wall and you will see the Blunt Cut Wires.
- (2) Blue, (1) 12v IT HAS POWER!!!! and (1) Trailer Brake Signal
- (1) Black Grnd.
- (White/Blue) Signal Wire
- Connect your Controller Wires
- Put Console Panel into position. Look at the lower back corner near the seat. Use a long screw driver to push the
lower tab into position 1st!
- Lightly push all of the taps in
- Now mount your controller.
