How to Install the Trailer Brake Controller on a 2014 Chevrolet Express Van


Today on our 2014 Chevrolet Express we're going to take a look at and show you how to install that the Tekonsha Primus IQ trailer brake controller. This proportional controller works great for one of the three axles. Its part number is TK90160. To test out of brake controller will either hook it to our trailer or a simulated trailer and slowly operate our manual override lever. As we do, we should see the amperage and voltage boosting up in our tester. That's going to indicate to us that our brake controller is sending the signal to the rear.

If this weren't connected to your trailer, you want to be sure that your trailer brakes we're engaging. To do that you could just lift up one tire spin it apply the override lever and make sure that that wheel comes to a stop. With the trailer connected you can see, we're going to have that small c as we head down the road. That c means well that we're connected. In the event of a disconnect this will start flashing NC that's going to indicate to us that we're no longer connected we need to check it out. The small red LED also indicates to us that we have power.

Our gain is fully adjustable will use . will turn our controller on by using the manual override. You see here the rotating dial as we bring that down that's going to reduce the amount of braking power going to the rear. See that as we go up that's going to increase it. This allows us to fully customize our brake controller for the trailer. Another great way of doing that is the boost control right up here on top.

You hit the button it will say b with nothing beside it that means we don't have any boost on. Then we have b1 b2 and b3 before we go back to the boost being off. That boost we raise that level depending on the weight of the trailer in relation to the vehicle. That's in the instructions. That can help dial that in.

That boost level is going to determine how quickly and aggressively our brakes are engaged. The Primus IQ is fully proportional we're able to mount this from 0 or flat level up to 70 as long as we keep it on the vertical plane meaning that it's in line with the direction of travel. The accelerometer that's inside is going to sense when we put our foot on our breaks to slow down the vehicle. Once it senses that it immediately starts putting braking power to the rear however we've got it set up here. This is a big advantage over the time delay brake controllers because we don't have to wait for them to engage. Those will slowly build up over a designated period of time where this one is going to give us that immediate response. We've got a nice LED display here. This is going to indicate to us as we're changing our boost levels. Easy to read display their whereas we're changing our gain will be able to see it very clearly. Manual override lever is very easy to get to. Nice and ergonomic where are we need to in an emergency we can reach up and get some breaks going to the trailer to help us out. we've got a couple of fail-safe that are built in here which sends a minimal drain on the battery. It's going to protect our battery from any kind of overdraw or drain situation, and it's also going to constantly monitor the trailer to make sure that we have a good connection. When we get into more, prolong stops maybe at a stoplight or something like that this is slowly going to reduce the amount of braking power that sent to her trailer that way they don't overheat. To begin our installation, we're going to find the pre-wiring. To do that will look just behind into the left of the brake pedal. There's going to be the main wiring harness here this is going to run up and down right here. Typically this bundle of wire is here light blue black red and blue is going to be taped to that but with this conversion, it looks like they just kind of moved it and tucked it down here behind the carpet. We'll get that pulled out here where we can work with it and the white piece of paper here . this should tell us what we need to wire to what. Alright we will look here we'll know that the blacks are ground the red and white that's going to be our battery, It will be our power wire the dark blue that's our trailer field our auxiliary and then the light blue with the white that's going to be for our brake light switch. Let's get this unwound here. To help out with her install, we're going to be using two of part number DW5714. That's going to be our 16 to 14 gauge butt connector, and we'll use one of part number 05732-2. It's going to be the 12 - 10 gauge butt connector and that's going to come as a quantity of two. You can see we've Connected or butt connectors here to the ends of our wires. We'll start making our connections dark blue that needs to go to our trailer brake line that's going to be the dark blue coming from a pigtail. Our red this needs to go to our brake light switch. Its going to be the light blue with white we'll strip that back just a little bit longer and just double that wire out to give us me to grab onto theirs. Let's connect that to our red wire our white wire here this is for our ground. It comes out of our pigtails and we know from our chart that our ground here's is our black wire. Let's connect those again strip it back and double what you need. Then finally our black this is going to be our 12-volt power, and we know here that's going to be our red and white wire. We just left our tape in there to make sure we didn't have any one of those shorts or anything when we are working with the rest of them. Let's get the end of that striped back. Be careful when you know, we got it bare here not to let it make contact with any ground points and will make that connection right there. For the sake of keeping a nice clean look and also protecting our butt connectors just go ahead and wrap it up with some tape. We're going to mount our bracket. You can see our bracket is a little bit out of shape. That's intended typically this is going to sit nice and flush up and down on each side. It's going to be square 90-degree corners. In this application, our dashboard is a little bit rounded here. We've put a little bend in the top, and we also need to adjust the angle. If we we're to mount our brake controller in here, it would be sitting sideways. What you do is use the top set of holes on our left side the bottom set of holes on our right that's going to adjust it down to accommodate it, so it looks appropriate we've bent each of our angles from here in this one out just slightly. Notice the side of my location which is going to be right there. We'll just take the provided self-tapping screws go right into a mounting surface, of course, we need to check behind. Make sure we don't have any wires or anything running in there and we'll just get it secured. We'll bring our pigtail around the backside of the brake pedal there. It's going to plug right into the back of the brake controller as you can see. We've got the NC means nothing connected or no connection and in the side we are going to have holes. There's going to be one on each side or two on each side. We just align those with the appropriate holes in the bracket. Then using the provided self-tapping screws you can get it secured. As you, cans see nice and secure. We just have to use a couple of zipping ties will tidy up a pigtail up there keep it up and out of the way. Well just tucker our wire right up here then just two zip ties will be all we need to keep it up and out of the way. We can go around . we have the factory wire room there to give us some support. We'll just trim off our excess there and . with everything properly that completes today's installation of the Tekonsha Primus IQ trailer brake controller part number TK90160 on our 2014 Chevrolet Express. .
