How to Install a Trailer Brake Controller on a 2013 Chevrolet Silverado


Today on our 2013 Chevrolet Silverado, well be installing the Curt TriFlex Trailer Brake Controller for one to four axles in the proportional style part number C51140. Additionally, well be installing the Curt Universal Wiring Adapter for Curt Trailer Brake Controllers part number C51515. Well being here over on the driver side underneath the dash. Well need to pull down the factor wires and well be using it to tie in with our brake controller. This here is the Curt Universal Wiring Adapter for Curt Brake Controllers. We need to connect these four wires to four of the wires here. Well be making these connections using some butt connectors. The butt connectors that well be using to make these connections are part number DW05714.

Well go ahead and make our butt connections. Now, were going to connect the blue wire with the blue wire, the red wire with the black stripe to the black wire, the white wires together and the light blue wire with the white stripe to the red wire followed by wrapping them up with some electrical tape to give them a little extra protection. Now, were going to need to go ahead and mount our brake controller as well as the bracket then go ahead choose an area on the lower dash here just below the steering wheel. Well be using this bracket here and a couple small screws that come with the kit. Lets go ahead and get our bracket mounted on the dash. Before we drill any holes to the dash, its a good idea to check behind to make sure that theres nothing that can be damaged. Well go ahead and put our bracket up.

We will need to take a small drill bit and put two pilot holes on the dash. Now that weve got one of the pilot holes drilled, well go ahead and put a screw in to help hold the bracket in place so we can make sure that its nice and leveled before we drill the other pilot hole. Now, to mount the controller box to the bracket, well be using these two holes here as well as the two holes that line up on the controller itself. You can see here how this one here has kind of pivoting action. This will allow you to put the brake controller to a different angle. Now, were going to go ahead and take some electrical tape and wrap the wires that come out of the back side of the brake controller just to clean up the appearance a little bit. Now, well go ahead and route the end of our universal harness to where well make our connection at the back side of the brake controller.

Well use a couple zip ties to help secure any excess wire up underneath the dash. Once we have all the wires secure, well go ahead and use a pair of cutters to trim off any excess zip tie. Now, were underneath the hood of the vehicle. Were over here on the driver side. Well need to take the cover off the fuse box and make two connections. The wire that well be connecting is in here between the fuse panel and the edge thats under.

As you can see here on the end of the fuse panel, one of the wires has already been connected so instead of connecting two wires, well only need to do one. Well go ahead and take the end of the wire with a ring terminal on it, slide it over the stud and then thread the 8 mm nut down on it and thats part number 185917. Well then go ahead and use our wrench to tighten it down. Now, we can go ahead and put the fuse box cover back in place. Now, when you plug your trailer in, the TriFlex will first give you a read-out of CC and then two dots. The two dots means that its ready for setup and the unit is calibrated. Now, lets go over your free features. Heres our manual override. This top round knob here or roller knob is what adjusts how much output the brake controller will go. You turn it towards the left or counter clockwise, it will lower the amount of output given to your trailer brakes. You turn the knob clockwise, it will increase the amount of power given to your trailer brakes. You will need to fine tune this for your particular trailer. This knob here, its a slide knob, its the sensitivity adjustment. The L1 as you see on the screen is the least aggressive. If you continue to slide it towards you, it will go all the way up to L9 which is the most aggressive or how quickly or aggressive the brakes will be applied to your trailer. The lower the number, the less aggressive the brakes will be applied. With that, that will conclude our installation of the Curt TriFlex Trailer Brake Controller for one to four axles in the proportional design part number C51140 on our 2013 Chevrolet Silverado. .
