Under Hood Wiring For Tekonsha Prodigy P3 Brake Controller Install on a 2013 GMC Yukon XL

Question:

I purchased a p3 controller for my 2013 GMC Yukon XL- I have a factory tow package- on the fuse box in the engine compartment there are TWO lugs, so I need to attach something to both of these lugs? I have located the wire in the fender well For the power but not sure if there should be another wire- please help!

To install a Tekonsha Prodigy P3 Trailer Brake Controller # 90195 on your 2013 GMC Yukon XL there are 2 wires that will need to be connected under the hood. The wire you found in the fender well attaches to give power to the brake controller. The other wire is for the charge line(see image) and this wire is hit an miss if it is already connected. You can see the 2 front posts on the front of your fuse box to see if the charge line wire is already connected with the M6 Nut # 185916. The M8 Nut # 185917 secures the brake control power wire from the fender.
