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.
And we are back behind the bumper now. As you can see, the socket that we removed earlier and plugged back into the back of the PK11916. We are back inside the cab now, down below the steering column down by the brake pedal. If you look up under here, you can see a bundle of wires taped up with this white tag. This is going to be the bundle for our tow package for the brake controller itself. We want to cut those wires down to give us a little more room to work with. Alright I went ahead and pulled all the wires out here and the brake controller that we are using is going to require you to purchase a universal plug as well, the 20127. It is going to have the 4 loose wires here. We are going to connect the red wire here off of the GMC into the black wire. The dark blue is going to connect to the dark blue. The light red on the harness here is going to connect to the light blue. Once the connections are made, I am going to go ahead and tape them up with electrical tape. OK, now that we have the plug wired in, we just want to find a suitable mounting location for the mounting bracket.
Typically you want to mount it to the right side of the steering column, somewhere in this area, somewhere where you can easily access it in an emergency braking situation. On this particular GMC, there is actually a roll under flange here on the bottom side of the dash that will allow the brake controller bracket to sit flush here. And that will make a pretty good mounting location there. That is where we are going to go ahead and mount it. With the brake controller now mounted in place, you want to go ahead and route the wires up into an area where you are going to be away from anything that is hot or moving, such as the brake pedal, the gas pedal, etc. We just want to go ahead and plug into the back of the unit. Once we have it plugged in, we want to go ahead and zip tie the excess wires up and out of the way.
We are under the hood now. We need to finalize the connections for the brake controller. We are going to have to actually remove the cover here for the fuse. There are going to be 2 wires that we need to connect. The first one is the power feed for the brake controller which is located right here on the side. We are going to run that directly to this post here. The accessory power 12 volt feed, which is right here with the ring terminal. Again it is taped to the harness here and we need to cut the tape and it is going to run directly to this post here. The ring terminal for the brake controller here is actually going to go on the far post. The ring terminal for the hot lead, the 12 volt lead for the plug, is actually going to go on the far post over here. For these posts, you are going to need to proved your own nuts to tighten these down. You will also need to fuse these as well. The post for the brake controller needs to be fused with a 30 amp fuse. The post for the hot lead will need a 40 amp fuse. This concludes the installation of brake control part number 5520 on a 2008 GMC Sierra.

Today on our 2002 GMC 2500, we going to be showing you how to install the Hopkins InSIGHT. This is a Proportional Flex-Mount Trailer Brake Controller for one up to four axles. We're also going to be using the Hopkins Plug-In Simple Brake Wiring Adapter, part# HM47795. The nice feature of the InSIGHT is that it constantly monitors our trailer, to make sure we have a proper connection. With the trailer plugged in, you'll see this small LED light is going to come on. As long as that's on, you know you've got a good connection with your trailer. If it we're to come loose or wiggle out, for some reason, you'll see that light then goes off. As you see here, our display is going to indicate, in percentage, how of the gain that we've got set we're actually using.
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.
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.
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.
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.
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.
