Today on this 2009 Chrysler Aspen we are going to install part number 90885, the Prodigy P2 brake controller. We are also going to use the install kit, part number ETBC7. The first thing we are going to do is install the bracket for the ETBC7 kit. We are going to install it right next to the hitch. And we are actually going to mount the bracket backwards so we can hide the connector a little bit behind the plastic on the bumper cover. The next step is to go ahead and do some partial assembly on the 7-pole itself. What we will do is we will go ahead and add the gray cable and we will hook it up to our 7-pole connector. What we are going to do is actually just wind this up with 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 wires. Our white wire is going to go directly to the frame for ground. And then the purple wire is going to be for reverse lights, if it is ever needed. 1:01
And to our black and blue wire we are going to install a gray cable which has the black and white wires inside of it. What we are going to do is just peel away the gray sheath and stripe 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. Alright with that assembled now we can go ahead and install it on to the bracket. Let us go ahead and connect the two 4-poles together. This is the one from the ETBC7 kit and this is the preexisting 4-pole that is on the vehicle. We will pack them full of dielectric grease and we will go ahead and tape them shut and run a zip-tie around them just to make sure they stay together. Ok, next we will go ahead and route our wires and tuck them safe, out of the way. We will leave that alone for now. Let us go ahead and tape up our wires and have them safe out of the way. Next we will go ahead and take the ground wire and just ground it directly to the frame. Now we will go ahead and continue running our wire up to the front of the vehicle, up to the engine compartment. Once you pull the wire up, route it over to the battery. Make sure you have enough length to reach the positive terminal on the battery. 2:30
We are going to have to remove the sheath and separate the black and white wire. The black wire is going to continue on going to the positive terminal of the battery. And the white is actually going to get run inside and hooked up to the blue wire on the brake controller. Let us go ahead and route our black wire back over to the battery. Let us go ahead and find a place for our circuit breaker. This is going to be the 40 amp circuit breaker and this is going to be for the 12 volt power supply which we are working on right now. We are actually going to mount it in this pocket right here and we will run our wire across the terminals and up to the battery. And next to our wire we will go ahead and add our two ring terminals. The small ones will connect to the circuit breaker. And then the other half of this wire we will go ahead and cut it to length as well to match up to our terminal here on the positive side. We will add our ring terminal to that. That will be one of the larger ones. Ok, we will go ahead and hook these up to the circuit breaker. The output going to the 12 volt power supply will use this silver post. And the wire going out to the battery will be using the copper post. And our connection going to the battery, we will actually save that for last. Now we are going to take our white wire. This is going to be run to the blue on the brake controller wire. There is a grommet on the inside that we can use. So what we are going to do is take our wire from the inside and pull it to the outside. Then pull this through. Ok, we are going to pull this on back through. 4:01
Alright let us cut off our excess wire. And since we are in the vehicle, let us go ahead and start mounting up the brake controller as well. We can start making our first connections to the brake controller. We are actually going to hook up our white wire that we ran earlier. We will hook it up to the blue wire. Next we will go ahead and deal with our red wire and we are going to run this to the cold side of the brake switch. So that means, every time we hit our brake pedal we have signal coming through the red wire. Follow the brake pedal up until you find the electrical switch and look for some wires that come out from the side. Alright, we will go ahead and take our tester and we will ground it to part of the inside of our vehicle. We are just going to test the wires to see what we have. That is the wire we want. And it looks like a white wire with a tan stripe. We will use a quick splice that is included with the ETBC7 kit. We will attach it to the wire we want to tap off of. The next two wires we need to deal with are the white and black wires. Now what we are supposed to do is go ahead and use that remaining wire that we have left over. However, it is going to be a little bit on the short side. So we are actually going to get another length of wire to make this run back to the battery. Go ahead and take the wire. Now it is going to be easier to push this wire from the inside back out. And just go ahead and pull back the sheath and connect it color for color. And we will go ahead and tape these up. Bundle them up safe and out of the way. 5:47
We are underneath the hood again. So let us go ahead and route that wire back over to the battery. Let us go ahead and mount our second circuit breaker. This is going to be the 20 amp. Pull back the sheath on this wire as well because the white wire is going to go to ground and the black wire will go to the circuit breaker and then on to the positive terminal of the battery. Measure our length and we will add the ring terminals again. And on the other half of the short wire we will go ahead and add a large ring terminal. Hook them to the circuit breaker. Going out to the brake controller we will use the silver post and out to the battery we will use the copper post. Let us move on to our white wire and that will go to ground. That will be the negative side of our battery. And we will add another large ring terminal to it. Alright, now we will go ahead and make our connections to the battery. Our connections are done to the battery. Go ahead and try out the brake controller on your trailer or tester. That will finish it for our install of the following parts: part number 90885, the Prodigy P brake controller and the part number ETBC7.
