How to Wire Dexter DX2 Brake Controller on 2013 Chevrolet Silverado

Published 10/04/2019

Question:

I was referring to the red/wblack stripe wire on the truck. Your instructions neglect to mention that this wire is NOT connected to the fuse panel. It is tucked under the harness that goes into the fuse box and needs to be pulled up and connected to the stud outside the fuse panel, but uder the cover.

The red wire from your Dexter DX2 brake controller # 58-8 needs to be wired to the cold side of the stop light switch, which on your 2013 Chevy Silverado corresponds to a light blue wire with a white stripe. This wire should ONLY be hot when the brake pedal is applied.

The rest of the wires actually match up with the same color wires on your truck as follows:

Dark blue on brake controller - To dark blue on vehicle
White on brake controller - To white on vehicle
Black on brake controller - To black on vehicle

I've attached a video of a similar brake controller being hardwired to a 2013 Silverado. The wiring process is the same so you can use this video as a reference to install your Dexter DX2 brake controller.

I understand what you mean now; sorry for the confusion. Brake controllers like the DX2 are not vehicle specific so the instructions that are included are a universal guide to the installation process as different vehicles may or may not require extra fuses/relays, trailer-tow package activation, etc. I pulled up a copy of your 2013 Chevrolet Silverado owner's manual that explains what you just found. The fuses for the red (battery feed) and dark blue (trailer brake) circuits are installed in the underhood electrical center, but the wires are not connected. The manual goes on to state that these should be connected by your dealer or a qualified service center. Note that the fuse/battery feed is not required if your vehicle is equipped with an auxiliary battery. "
