Trailer Brake Controller Installation - 2008 GMC Sierra

Today on our 2008 GMC Sierra we'll be installing the Tekonsha Prodigy P2 Trailer Brake Controller, part number 90885. See here this is our manual override. NC, that means there's no trailer connected to our truck. On this side you have your knob that adjusts the power for your brake controller and the button on top, that will change the boost level of your trailer brake controller. The boost adjusts how aggressively your brakes come onto to your trailer, depending on the size of your trailer and the weight you are hauling. Now we'll go ahead and hook our trailer up and test out our brake controller. We don't have a trailer plugged, in so it'll be no connection.



Tekonsha Prodigy RF Wireless Trailer Brake Controller Installation - 2003 GMC Sierra

Today on our 2003 GMC Sierra 1500, as well as our enclosed trailer, we're going to be installing the Tekonsha Prodigy RF Wireless Trailer Brake Controller, part number 90250. We're going to go ahead and start here underneath the hood of the vehicle. We're going to need to gain access to the underside of this fuse box and we need to hook up our wire. Now, this particular truck does not have the 12-volt power supply of the 7-way hot yet. That's the reason why we're going to need to get into this fuse box. To do that, we're going to need to remove these 4 bolts here, as well as lift this bracket out of the way. Next, we're going to go ahead and lift the cover off our fuse box.



Trailer Brake Controller Installation - 2011 GMC Sierra

Today on our 2011 GMC Sierra, we're going to install part number 90885 from Tekonsha. It's a Prodigy P2 Brake Controller. First thing we need to do is go ahead and locate the wire harness underneath the dash of the truck. Also, there's a small flag that helps identify the wires for it. It usually comes off the wire harness. In this case, it was stuck to a different wire harness but we pulled it out and away so you could see it.



Trailer Brake Controller Installation - 2003 GMC Sierra

Today on our 2003 GMC Sierra, we'll be installing the Tekonsha Prodigy P2 brake controller, part number 90885. We'll be using this brake controller in conjunction with the Tekonsha direct fit plug-in wire adapter, part number 3015-P. First we'll need to remove the cover on the manufacturer's junction box. We'll remove the plastic nut and then the cover. Located on the top row, second set of connection pins from the left will be a direct fit plug for our Tekonsha plug-in wiring adapter. While I plug into it, we'll start routing the wire over to our brake controller location, which will be towards the center of the vehicle just to the right of the gas pedal.



Trailer Brake Controller Installation - 2011 GMC Sierra

Today on our 2011 GMC Sierra we'll installing Tekonsha Prodigy P3 Brake Controller, Part Number 90195. To begin our install we'll first locate the manufacturer's brake control port wiring. Here on the driver's side in front of the fuse panel taped to the manufacturer's wiring will be the brake controller wiring. Now to access the brake controller port wiring, it'll usually be taped to the manufacturer's wiring so you can simply cut it free. Ours is not, so we'll just go ahead and pull it down. Now, go ahead and straighten it out and then cut each wire to the same length stripping back the wires. Now, with the manufacturer's wiring prepared we'll go ahead and add the butt connectors as necessary.

Today on our 2012 GMC Sierra, well be installing the Tekonsha Prodigy P2 Brake Controller, Part Number 90885. To begin the install, well first go ahead and locate the manufacture's brake controller pigtail. This pigtail will be taped to the main wiring harness near the brake pedal. Once we locate the wiring, well go ahead and pull it down to gain access to it. Now, there are a total of five wires. However, we will not be using the orange wire, just the red with the black tracer, blue with the white tracer, and white wire. Now, well go ahead and pull the wires down, and cut them out evenly the length. Then well strip each one of them back, and add a butt connector supply with the brake controller. Now, with butt connectors on the manufacture side, well bring in the brake control pigtail, which is supply with the brake controller, and start connecting our wires.



Trailer Brake Controller Installation - 2005 GMC Sierra

Alright today on this 2005 GMC Sierra, we are going to install part number 90885, the Prodigy P2 brake controller and part number 3015-P, the brake controller adapter. First step that we need to do is to remove this cover for access to the port that is behind here. So we will undo this nut and pop the cover off. We will take our cord and just plug it into place. Moving on, we will reinstall the cover and then put the nut back into place. Alright next we will go ahead and install our brake controller bracket and we are going to do that on a sheet metal at the bottom of the dash here.



Trailer Brake Controller Installation - 2008 GMC Sierra

Today we are going to be installing a brake controller on this 2008 GMC Sierra. The part number is 5520, along with the 7-way replacement socket for the GM products, part number PK11916. We are going to start in the rear, installing the 7-Pole replacement socket. We are back behind the bumper here and if you can see this unit here is actually the 7-pole factory socket that we are going to be plugging into. So we want to go ahead and disconnect this off of the knockout that goes into the bumper. We are back on the outside of the bumper here and this knockout here is actually going to be removed. This is where the PK11916 is going to be put in place of. Now that the knockout is removed, we want to go ahead and put the replacement socket in there. It just slides in and you want to line up the notches and just rotate it and it locks right into place. I am going to take the socket that we removed from the backside of the knockout earlier and plug it into the back of the 7-way here.





GMC Sierra Brake Controller Questions and Answers


  • Trailer Brakes Lock Up when Connected to 2014 GMC Sierra 2500HD with OEM Brake Controller
  • Your 2014 GMC Sierra 2500HD has an industry standard 7-Way trailer connector. It is possible that the one on your trailer is not pinned out to match. In other words it may have the 12 volt circuit switched with the brake output circuit and that would be why the brakes lock up when you plug in the trailer. I have included a picture that shows the way a trailer side 7-Way should be pinned out. Ignore the wire colors though and focus just on the functions. There is no industry standard...
