How to Install a Brake Controller for a Trailer on a 2003 Chevrolet Express Van


All right today on a 2003 Chevrolet Express Van we are going to install Prodigy brake controller part number 90185 from Tekonsha. We are also going to use part number ETBC7 as the install kit for the brake controller. Lets go ahead and mount the bracket from the ETBC7 kit. We actually want to mount it right onto the bumper itself. All right we will go ahead and do some sub assembly to our 7-pole here. Inside the cable here there is a black and white wire. We are actually going to go from color to color, almost color to color. Black to black and then white to blue. So we are going to connect our wires black to black. Then we will go from white to blue. Okay now lets go ahead and use some electrical tape and bundle it all together. All right now we will install the loom over that. We can go ahead and install our wire harness into our bracket here. Go ahead and push our wire harness over the hitch. 01:15

All right we will go ahead and connect the two 4-poles together. Go ahead and add some contact grease to protect them and we will just push them together. What we will do next is run a zip tie around both of them to kind of help keep them together forever. All right we are going to thread our cable through just a little bit through the frame to keep it out of the way. Now we are going to use a number 14 screw that you can get from a local hardware store that matches perfectly with this eye loop right here. Okay what we did is pushed our wire through the frame here over the suspension and we actually got it to come out of this hole right here. Next we will go ahead and run our wire up to the front of the vehicle along with the frame rail or inside the frame rail as best as possible. 02:18

What we are doing is mounting our wiring up and staying away from the exhaust as far as possible so it is best to take a slight detour down to the wire harness here. All right now we have got our wires ran underneath the vehicle. Lets go ahead and zip tie these together so they will be safe and up and out of the way. All right go ahead and reach down and pull out the wire and then thread it through up so it does not touch anything hot or any other moving part. So we are going to start from this point and go ahead and take the sheath off. This white wire is going to go to our brake controller so we will push this back over. Then our black wire like I said is going to be for our 12 volt power supply so we are going to run that over to our circuit breakers and battery. To make things a little it easier what we are going to do is one, we are going to take off this crossbar right here and pull the support it will come out with two bolts easily. And also we are going to go ahead and just disconnect the battery and take that and get it out of our way also. We are going to use our 40 amp circuit breaker for our hot lube going out back and then we will use our 20 amp circuit breaker for the brake controller. I am going to take our wire for our 12 volt lead and connect the 40 amp circuit breaker right here and then on this one here and then we will go from our copper one over to the battery. Do the same thing on our other half of the wire going to our battery. 03:39

This lead now we will go ahead and leave it loose and to make the connection to the battery is one of the last things we are going to do. All right we went and got ourselves an extra eight foot long piece of wire and basically what we are going to do is strip the sheath off again about a foot or so and then we will make our connections to our circuit breaker and run it back over to where the firewall where we are going to run it through there. All right that will go to the silver post on our circuit breaker and on the other half we cut loose will go to the copper side and go out to the battery just like the other ones. This white wire is going to go to the ground on our battery so we will leave that alone for now. It would be a good time to rehook up the battery. So I am going to go ahead and replace these connectors to some new connections and then basically extend it out and we can attach our brake controller with. We got those at the local auto parts store. Next we will hook up our ground connection from the brake controller. We are going to use this ground right here in the body. It has got a good solid connection that is straight off the battery. We will go ahead and use that. We will go ahead and add these ring terminals. These will both go on the positive terminal on the battery. All right the wire is ran back over to the other side now. All right what we are going to do now is go ahead and drill our access hole. What we are going to do is after drilling into your interior plastic here we will go through it with a hole saw through just the plastic itself and then we will use a smaller hole to run our wires through. 05:39

Okay we have got our grommet in place. We will go ahead and poke our wires through the grommet. All right we will go ahead and hook up our brake controller wires and remember our normal white wire was going out to our blue wire on the 7-pole so we are going to hook up our blue wire back on the other end of this. Off the ground and battery it is still going to be color for color. All right we will go ahead and test for our brake signal. Most of the time it is going to be a white wire. That is our brake signal so go ahead and attach to that. We have got a quick splice to do that with. Go ahead and start mounting up the brake controller underneath the dash. It is going to sit about right in this area right here. All right we are going to plug in our port into the back of your brake controller. Go ahead and take our wires now and go ahead and bundle them up safe and out of the way. All right we have got power on our brake controller and you have got two dots. When we hit the manual override we get the NC which means no connection to the trailer because we do not have anything connected up. This one dot tells us we have power going to the brake controller and this one here tells us that one of the boost functions is set. Right now we are at boost one, boost two, boost three, and the fourth one turns off the boost setting and we just have the one dot. All right with the load on it we have C for connection so that is good. We need the manual override and that works. Just for gain setting down to zero. We will set it back up to six just for testing purposes. All right and that shows that our brake controller is working. That finishes our install of brake controller 90185 from Tekonsha part number ETBC7 as the install kit for the brake controller on a 2003 Chevrolet Express Van.
