Dodge Grand Caravan Brake Controller



Installation of a Trailer Brake Controller on a 2010 Dodge Grand Caravan


Today on this 2010 Dodge Grand Caravan we are going to install part number 90885, the Prodigy P2 brake controller. And we are also going to be installing the ETBC7 installation kit. And we will also be using a bracket from Tow Ready, part number 118136. OK, we will start off with part number 118136. We will attach that to the hitch and that will allow us to attach the 7-pole to the vehicle. Next we will get the 7-pole and do some sub-assembly first before attaching that to the vehicle. What we are going to do is actually wind thus up in electric tape and leave our leads out that we need. We will leave our 4-pole sticking out. And we are going to need our brake wire which is going to be blue and our black wire for 12 volt power supply. And then we will just wrap up our purple and white wire. Our white wire is going directly to the frame for ground and then the purple wire is going to be for reverse lights if it is ever needed. 0:50

In to our black and blue wires we are going to install the gray cable that has the black and white wires inside of it. What we are going to do is just peel away the gray sheath, strip our wires back and make our connections. And we are going to go black to black and white to blue. Cover those up with some electric tape. Next we will go ahead and install the loom along the wires like this. The next step is to take the existing 4-pole and plug it into the 4-pole that is with the ETBC7 kit. We will pack it full of dielectric grease and then we will go ahead and zip-tie it together. Alright, we will take our wire starting with the gray end and we will thread it to where we want it behind the bumper and we will make our initial start towards the front. Alright, once we have our wires going in the direction we want, we will go ahead and zip-tie them down to hold them in place. 1:55

Next is to go ahead and attach our ground wire to the body right here. We will use this cross member. That will work just fine. And we will be using a number 14 self taping screw to attach it. Next we will go ahead and run the gray cable up to the front of the vehicle, making sure we stay away from anything that is moving or gets hot like the exhaust. We pulled the wire up out of the way. We will just leave it alone for now. We will start mounting our first circuit breaker. This will be a 40 amp circuit breaker. This will supply a 12 volt power supply going out back to the 7-pole. Let us go ahead and tie off our wire and see how much length we need to go to our circuit breaker and then down to the positive side of our battery. OK, once we have that established, we will go ahead and zip-tie off the wire to hold it in place for us. And we know we only need about this much of wire. However, we are going to cut it longer because we need some of the white wire to run back to the brake controller in the inside. Alright, now we will go ahead and cut the sheath away so we have access to our wires. Tuck our white wire away for now. And our black wire we will run over to the silver post. We will add a ring terminal to that and then the copper post will go straight to the battery. And we want to cut a length for that as well. We will add the small ring terminal. And then our short wire, we will add the other two ring terminals. So add that small ring terminal to the copper side of the breaker. Now the other end will go to the positive post. However, we will leave that as one of the last things we will hook up after everything else is installed. 3:50

Now to get to the inside of the vehicle, we are going to have to cut through this grommet right here as you can see from the outside looking in. We will have to make our cut from the inside out. And we are just going to take a knife and cut through the top of the grommet, away from the wires. Now it is double walled, so if this knife is kind of short you can use a long pocket knife to go to the other side. If you do not have that, then you can use a screw driver and poke through the other side as well. We will go ahead and use a piece of wire to push from the inside out and use that to pull the white wire back inside the vehicle. And we will just simply tape the two ends together and pull it back through. While we are in the vehicle, we will go ahead and discover which wire we will need for our brake light signal. OK, for our brake light circuit we have to find that coming off the brake switch. We followed our brake pedal up to the brake switch which is located right here. And it is kind of hard to get to. But if we follow the wire harness over, we came over to this harness right here and did our testing here. And the colored wire we found was white with the green stripe. So we know where our brake signal is. We will go ahead and hook our brake controller wire up to that signal. Now our brake controller wire will be red. We will be using a quick splice connector to make our connection. Let us deal with our white wire here. If you remember, that gets connected to the blue wire on the 7-pole connector. So that will be reconnected to the blue wire coming out of the brake controller. Now the only two wires we have left over are the black and white. And we will use our excess wire that we had from before in the gray sheath cable to run that from the inside back out. The connections are made. Let us go ahead and take our wire and poke it back through the grommet to the outside. Go ahead and tape up our connections. And then we will bundle our wire together and make it nice. Alright now we will find a place to mount our brake controller. This little flat area right here will do just fine. Just make sure you space it far enough away that you can get back here with tools to install the hardware on the side. 5:58

We will check with the brake controller. Make sure everything will fit ok. Go ahead and take our wire harness. Plug it into the brake controller and bolt it to the bracket. Zip-tie the brake controller up and out of the way. We are back underneath the hood. Here is our wire from the inside out, coming straight from the brake controller. We will go ahead and add our next circuit breaker. Now the kit comes with three circuit breakers. You only use two out of the three. Check the documentation on whatever type of brake controller you use to see which breaker you need. We will go ahead and attach it right here. OK, we will go ahead and cut our wire to length. We need it long enough to run to go to ground on our battery and take our black wire and run it over to the positive side. Alright, we will take our black wire and we will hook that up to the silver post on our brake controller. And we will go ahead and cut it to length and add the ring terminal. We will take our other length and we will add two ring terminals to it, one large one and one small one to each end. Let us go back to our ground wire and we will install a ring terminal for that as well. With all of our wires ready to be installed, let us go ahead and make our final connections to the battery. The next thing is to go ahead and check our brake controller and see if it has power. We will go check in on our brake controller. And you can see that we have two blue lights, one light is for power which is good and the other one shows that it is on a boost. And there you have it for part number 90885, the ETBC7 installation kit and 118136.

Trailer Brake Controller Installation - 2009 Dodge Grand Caravan

Today on our 2009 Dodge Caravan, we'll be installing the Tekonsha Prodigy P2 brake controller, part number 90885. Note, this vehicle has already had an ETBC7 brake controller installation kit installed, so we'll be connecting to it and mounting our brake controller. So to begin our install, we'll take the pocket from our brake controller and install the pocket onto the dash. We'll be installing it on the kick panel to the passenger side of the steering wheel. We'll use the hardware provided with our install kit to secure it. Next, we'll take the wiring harness from the brake controller and secure it to the vehicle.



Trailer Brake Controller Installation - 2008 Dodge Grand Caravan

Today on this 2008 Dodge Grand Caravan we are going to install brake controller and we are going to be using part number 5520 the Activator 3 from Draw-Tite. We are going to be using a bracket part number 118136 from Tow Ready and we are going to be using brake controller install kit part number ETBC7. We will begin our install by installing our bracket on the hitch and we will clamp it into place using the supplied clamp. Next we will take the 7-pole bracket and install that next onto the bracket that we just did. Next thing we need to do is prepare the 7-pole that comes with the ETBC7 kit and get it ready to install in our bracket. What we are going to do next is connect our gray cable to our 7-pole cables so basically we are going to strip this back and make our connections. We are going to hook this black to black, and this black wire is going to go straight up to the battery for our 12 volt power supply and that is it. This white wire is going to go to the blue wire that is going to go to our brake controller so when we go back up to the brake controller this white wire will go back up to the blue. 01:03



Trailer Brake Controller Installation - 2008 Dodge Grand Caravan Part 2

To get to the engine compartment, we are going to drill out a hole right here, between this grommet and this smaller grommet up here. We are going to start off with a 1/4 inch and work our way up so we can install our bushing, which will end up right in there. Be careful of the wires right next door. Once you have your holes drilled out, you can go ahead and insert your bushing of your choice. And at this point you can take the extra wire that you had and wire going to the brake controller going out to the connector you can run those through right now. We are going to run outside our blue wire going out to our trailer, our white wire is going to go to ground, and our black wire will eventually go to our power. To give yourself a good idea about how much wire to leave left over behind so you have enough to reach the brake controller when you install it and it is always a good idea to have a little bit extra on the inside. So we will push a little back in there towards the outside. 1:05



Trailer Brake Controller Installation - 2008 Dodge Grand Caravan Part 1

Today, we are going to install part number 90185, the Prodigy brake controller from Tekonsha and we are going to install this on an 08 Dodge Grand Caravan. Also, on this install, we are going to be using part number ETBC-7 and also part number 118140 bracket kit. First, we are going to install the 18140 at the rear of the vehicle on the hitch. There is a hose clamp that holds it in place, basically. Kind of hold everything in place and just tighten it down. Now, we will install the bracket for the ETBC-7 kit and we will just put it on like so. Next, we will install the connector and it just goes into place like so. Put a couple of screws to hold it into place. Alright, at this point we will connect up to the preexisting 4-pole we already have. Next, we will put the existing 4-pole to the connector and before we do that we will put some dialectic grease in there keep it from corroding up over time. And we will put a zip tie around it make sure that it never comes apart. What we are going to do next is run our ground wire that will be the white with the ring terminal and then the purple wire is reverse light lead. In this instance we will not be hooking it up, that is because the trailer does not have any back up lights on it and also since this has to have a modulite for the wiring harness the reverse lights are not powered by the modulite, so it probably would not be a good idea to hook them up anyway. And then we will ground our ring terminal at the body panel near the pinch weld. Now, we will just go ahead and secure our wires to our other wires underneath the bumper. Next, what we need to do is go ahead and hook up our leads that go to the front of the vehicle. The blue will be going to the brake controller and the black will be going to the 12 volts basically straight to the battery going through a circuit breaker. We will just strip the ends off of the wire and we are going to go black to black for our 12 volt power supply and we are going to hook our white wire it is going to go to our blue wire. Just remember that the white wire is going to be going eventually back to the blue wire on the brake controller. We will go ahead and secure the wires with some tape, bind them up. Once you have them taped up secure, you can go ahead and install the loom assembly around it. It kind of slides onto the wire. You can also take the rest of your wires here and put it with it also. 2:33
