Today on this 2010 Dodge Nitro we are going to install brake controller part number 90885 from Tekonsha. This is their Prodigy P2 brake controller. And to install this, we are going to use part number ETBC7. The first thing we need to do is go ahead and take the bracket from the ETBC7 kit. We are going to install that on to the bracket that is on the hitch. 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 that comes with the kit and we will hook it up to our 7-pole connector. What we are going to do is actually just wind this up in electric tape and leave our leads out that we need. We are going to leave our 4-pole sticking out and we are going to need our brake wire which is going to be blue and out 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. And to our black and blue wires we are going to install the grey cable that has the black and white wires inside of it. What we are going to do is just peel away the grey sheath. Then stripe our wires back and make our connections: 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. 1:20
Let us go ahead and mount the 7-pole to the bracket now. Now let us go ahead and connect the two 4-poles together. And we will just pack it full of dielectric grease to protect it. And we will make a solid connection out of it. We will use a zip-tie to secure it together. Then we will cover it up with some tape. Ok, now let us take our grey cable and let us start routing it to the front of our vehicle, up by the engine compartment. And we want to stay away from anything moving, such as suspension components, or anything hot like the exhaust. We will take our white ground wire with a ring terminal and we will go ahead and ground that to the body. We are using this crossbeam right here. We will go ahead and pull up our wire now. Make sure it stays away from anything moving like the suspension or steering components as well. Alright, now we are going to take our wire and we are just pull it off to the side and just let it be for now. Next we will go ahead and install the 40 amp circuit breaker. I think we will install our circuit breaker in this spot right here. And we will have to add one eventually so we will have to leave room right over here. Alright, let us take our cable and see how much length we will need to go to the positive side of the battery. Once we find that we will go ahead and cut it. And our excess wire here we are going to use later. So, do not through this away. 3:03
Now we will take this wire that we just cut and we will pull back the sheath on it because we only need to use the black wire inside of it for the 12 volt power supply. Our white wire inside will actually be ran inside of the vehicle to the blue wire on the brake controller. And we will go ahead and deal with the black wire for now. We will go ahead and cut the wire. We will add some ring terminals to it and connect it to our circuit breaker. Now our lead going out to the 12 volt power supply out back to the 7-pole is going to be hooked to the silver post. And then the copper post will always go to the battery. Alright, with the other end of the wire let us go ahead and add one of the larger ring terminals to it so it can connect up to the positive side of the battery. We will actually make all of our connections to the battery one of the last things we do. So we will just set this aside for now. Let us go back to our circuit breaker and we will go ahead and tighten down those studs. Ok, now let us start working with the white wire. We will go ahead and find an entry point so we can get from the outside to the inside of the cabin. If you look right next to the brake booster here, you can see a rubber plug right here. You can go ahead and pull that out. It does come out rather easily. Then we have full access to the interior. So what we are going to do with this is go ahead and make a slit in it so we can pass our wires through. Take our white wire and go ahead and poke it through. And then go to the inside. 4:35
Alright, now we are not going to reinstall the grommet because actually we have two more wires to pass through. So we will just leave it just like this for now. We have installed the brake controller. Now let us go ahead and connect the blue wire from the brake controller up to that white wire we ran inside earlier. Cut it to length and then we will go ahead and connect it together with one of the butt connectors. We have that wire connected. Now while we are here, let us go ahead and connect our red wire to the cold side of the brake switch. What we are going to have to do is follow the brake pedal up until we find the switch and find the wires. And we will have to test to see which one turns on when you hit the brake pedal. Let us go ahead and test our wire harness for the right signal. It looks like the white wire with the green stripe is we want. Alright, so we will take our quick splice that comes with the ETBC7 kit and we will slide it over the wire. Now we will take our red wire and slide it right next to it. Then we will squeeze down on it and make the connection. Alright, let us go take our excess wire that we removed before up front. We will go ahead and take it. We will poke it through the hole in the firewall and push it out to the battery. So we will connect these two wires up color to color to the brake controller wire. Alright, we will go ahead and take these up and go ahead and snug up everything underneath the dash. Make sure it is safe and secure, out of the way. 6:01
Ok, we are done underneath the dash. Now let us go ahead underneath the hood and make our connection to the battery. Alright, let us go ahead and take our wire we pushed through and we will put it back through the grommet. Pull it on through and we will reinstall the grommet at that point. When we run our lead to the battery, we need to install the circuit breaker like we installed a little bit earlier. We are going to install it right next to the first one that we installed. So it is the same thing as before. We will go ahead and run our wire through the circuit breaker to get our distance that we need. And we will cut off the length to the positive side of the battery. Same as before, we will go ahead and strip back the sheath as well, as far back as we need to. Let us put our white wire to the side. And with our black wire, run it to the circuit breaker. So our silver post will go to the brake controller and the other half of the wire will go to the battery. Now our white wire, we will go ahead and just run this directly to the negative on our battery, for ground. We will start off by removing the negative terminal and attaching the white wire to that. Let us leave that alone for now. Let us go start working with the positive terminal. The power is supplied to the brake controller. All you need to do now is test it and make sure everything is working fine. And with that that will finish our install of part numbers 90885 and ETBC7 install kit.
