How to Install a Roadmaster Tow Bar Wiring Kit on a 2014 Jeep Wrangler Unlimited

Today on our 2014 Jeep Wrangler Unlimited, we'll be installing the Roadmaster Universal Diode 4-Pole Wiring Kit, part number RM-154. We'll be installing this kit for a towed vehicle that will work in conjunction with the manufacturer's brake and turn signals. Starting on the passenger side, we'll go ahead and remove the taillight assembly. We'll need to gain access to the manufacturer's wiring behind the taillight assembly. With the taillight assembly out, we can go ahead and take the wiring loom and remove it, so we can gain access to the wires. Using my utility knife, I'll go ahead and cut the electrical tape and then cut off the excess loom. Next, using a test light, we'll go ahead and check the manufacturer's wiring to locate the running light circuit and then the single wire that will carry both brake and turn signal circuit. Here at the passenger rear taillight, the white wire with the yellow stripe is going to be the turn and brake signal circuit.

The white wire with the purple tracer is going to be our right rear running light circuit. We're going to be connecting inline with these manufacturer wiring. Next, we'll take the 4-pole wire and feed it up behind the driver's side taillight assembly. To do this, we'll need to run it from underneath, up behind the taillight assembly. We'll go through one of the manufacturer's pre-drilled holes. Now it has had spray foam applied to it from the inside, so we're going to go ahead and use a drill bit just to create a hole large enough that we can feed our wires through.

Once we drill out the hole, we'll then go and take the 4-pole wire and cut off the end as we will not need it here on the towed vehicle end. Then we'll feed it up through our drilled hole behind the taillight assembly. Now, for the passenger side, we'll be using 2 of the 3 pronged diodes. Note: We will not use the one with the yellow connector as it will be reserved for the driver's side where the two running lights will come together. We'll start with the turn and brake signal circuit. Take the white wire with the yellow stripe, cut it in half and strip back both sides.

We'll take the connectors in the diode and crimp them directly to the manufacturer's wire. Next, we can take the green wire and strip it back. Once we strip it back, we'll add a connector from our diode. Now we can go ahead and install the diode here for the passenger side rear turn and brake signal circuit. We'll have two spade terminals for the in and one spade terminal for the out. The out will go to the taillight.

One in will come from the vehicle side, and the second will come from our new 4-pole wiring harness. Now with our turn and brake signal circuit connected here on the passenger side, we'll repeat the same process for the running light circuit. We'll take the manufacturer's wire, the white wire with the purple stripe, cut it in half and strip it back. Wire connectors to both ends of the manufacturer's wire and a connector to our brown wire from our 4-pole harness. Then we'll go ahead and connect the diode, taking the out and plugging it into the connector. Then we'll go directly to the taillight. The other end of the connector will go to the manufacturer's wiring harness for the input, and then the other input will come from the brown wire on our 4-pole connector. Next, we'll take the white wire from our 4-pole harness, strip it back and add a ring terminal supplied with the install kit. This will provide the ground for the towed vehicle wiring for our new 4-pole harness. We'll take the ring terminal and then secure it to the body or sheet metal of the vehicle. Note: I recommend to find a location where the sheet metal doubles up. Here, on the inside of the body cavity, is a great location. Using a self-tapping screw, we'll go ahead and secure the ring terminal now. Now, with all our connections made, we'll go ahead and take our black electric tape and wrap up the connection points to help keep them from from dirt, dust, debris and moisture. Then we'll go ahead and reinstall the taillight assembly. Next, we'll get underneath the vehicle and start taking the new 4-pole harness and routing it over to the driver's side. Once we get to the driver's side, we can feed it up behind the driver's side taillight assembly. Now we'll go ahead and remove the taillight assembly. Take the 4-pole harness and run it up and out through the opening in the body. Here we're going to repeat the same process of installing two diodes. One will be for the driver's side turn and brake signal circuit, which we'll connect to the manufacturer's white wire with the green tracer. Then the other will be for the running light circuit here on the driver's side, which will be a white wire with an orange tracer. We'll be repeating the same process of installing our diodes with one exception: the running light circuit here. We'll be taking the brown wire from the passenger side and the brown wire from our 4-pole harness, stripping both of them back, twisting them together and, using the yellow spade connector to jump the two together. Theyll ultimately go up to the front of our 4-pole harness for our towed vehicle wiring. Once we've made all our connections, we'll then go ahead and feed our 4-pole harness back down underneath the vehicle and start routing it up to the front to our base plate. Keep in mind when routing your wires to as many moving opponents such as as the steering or suspension or excessive heat such as exhaust. For this application we'll actually be able to route the 4-pole harness inside the frame which will help protect it ultimately up to the front of the vehicle. We'll use zip ties provided with the install kit to secure wiring, if necessary. Once we have it to the front, we can then secure it to the base plate. We'll cut off the excess from the zip ties, clean up the install look. This will complete the install of the Roadmaster Universal 4-Pole Diode Wiring Kit, part number RM-154 on our 2014 Jeep Wrangler Unlimited. .
