Video of Roadmaster Tail Light Wiring Kit with Bulbs
installation instructions and specs for complete information.
Today on our 2014 Jeep Patriot, were installing a roadmaster tail light wiring kit with bulbs part number RM-155. Now, were going to begin up here at the front of the vehicle. Well go ahead and raise the hood up. Now, were going to take the long wire that has two four flat ends to it. Were actually going to cut one of the four flat ends off. Now the end that we keep that has a four flat connected to it, were actually going to mount up underneath the grill in this vehicle.Now, this vehicle already has a base plate installed so well be connecting it up here at the base plate.
Now were going to go ahead and route the wire up to the engine compartment and down behind the front fascia zip tying it off along the way. Were also going to make sure we leave a little extra wire underneath the lower fascia as well as in the engine compartment. If we have any future needs or if we want to change the way the plug is mounted, well have plenty of extra lead. Now that weve secured our four flat up underneath the lower fascia, were going to go ahead and route the wire up to the engine compartment and back down along the firewall.Now once we have all the excess wire pulled down underneath the vehicle, well go ahead and zip-tie it off along the way. Now that the wire is pulled down underneath the vehicle, were going to route it along where theres some other wires as well as some tubing that runs back to the back.
Now when routing your wire, you want to make sure you stay away from any sharp edges, areas that may move, or areas that may also get hot and damage the wire.Now youll also notice up underneath the lower front fascia, we used a section of the wire loom thats supplied with the kit as there was an area near the base plate that have been installed on this vehicle that had some very sharp edges and we wanted to give the wire a little extra protection. Now, well go ahead and route the wire to the back of the vehicle. To aid in the routing of the wire, were going to use a section of all the air line tubing which is a little more rigid and allows us to angle the wire in the direction that we want it to go. Now that weve got the wire routed to the rear of the vehicle, were going to go ahead and we need to remove the tail lights.To remove the tail lights, you need to raise the rear hatch of the vehicle and there are two pushpin fasteners on each side that will need to be take n out. A large flathead screw driver or a trim panel removal tool large grade for getting these out.
To remove them, you pull the center of the pushpin out. Once you pull the center out far enough, you can pull the whole pin out. Once youve gotten both pins out of each of the light assemblies, you simply work the light assembly off the body of the vehicle.There are two additional knobs or tabs that help hold the light assembly to the body. Once you have the light assembly worked out, there are two factory wiring harness connections that well need to undo. Each of them has a red locking tab that you need to undo first and then gently squeeze on the tab pulling it free from the light assembly.
Well go ahead and repeat the same process for removing the lights on both the driver and the passenger side. Once our tail lights are out, were going to go ahead and need a one-inch hole saw to drill a hole in the bottom section of each of the tail lights. It is in the red section that does not have an electrical connection behind it.Once we drill our one-inch hole in the center of each, well go ahead and take our light socket and were going to have to bend the tabs out slightly to make sure that we get a nice snug fit in our new one-inch hole in the back of the light assembly. It may take you several tries at bending the tabs to get it just right so you get a nice tight fit. A screw driver works well at bending these tabs out. Its a good idea to do a little bit at a time and keep test-fitting until you get the right fit. Its also a good idea to go ahead and strip the free wires before you push them into the light assembly. It makes it a little easier for making our connections later so were not pulling on the wires themselves once the socket is in the light assembly.Now that we have each of the socket bulbs installed in each of the light assemblies, now were ready to complete our wiring here at the back. Were going to go ahead and peel the green wire off the four flat. Pull it back far enough to where the other three wires will go up behind the rear fascia and into the light assembly area on the drivers side. Well go ahead then and pull the brown, the yellow and the white wire up into the drivers side light assembly. Once we have enough wire pulled up, well go ahead and snip off the excess here.Again, keeping the green wire a constant wire is well need to run this over to the passengers side. Now once we get up into the drivers side light assembly area, were going to go ahead and make some connections. Were going to take the extra wire that we just snipped off of the lead which will have the yellow, the brown and the white and we can peel the extra yellow wire off of this section as we will be connecting the two whites together. One that just run up from underneath and this new extra piece and the browns together.Well be doing this by using the yellow butt connectors that come with the kit. Now, the yellow wire that weve run up into this area, well also strip these in a blue butt connector. Well go on this one. Once we have this done, we can go ahead and connect our wires to the back of the socket bulb thats already in the light assembly. The yellow wire will go to the red wire on the back of the bulb assemble. The black wire will go to the white wires and the brown wire will go to the brown. Once we have all our connections made, well go ahead and tape them up and then we can put our light assembly back in place.Now with our light assembly back in place, lets go ahead and route our wires over to the passengers side. To do this, were going to route it underneath some of the brackets that hold the rear fascia in. Were also going to use a couple small pieces of sire loom to protect the wire where it goes over some sharp edges. Once we have these done, well go ahead and use some zip ties to help secure the wire along the way as well. Now once we have these three wires pulled over to the passengers side, again, well use the small section or air line tubing we had to help pull them up behind the rear bumper fascia.Now when routing our wires over to the passengers side, in this case, it will be a brown wire, a white wire and a green wire that we run from the front. We went ahead and used a little electrical tape to help connect these three together and keep them bundled up. Once we have the wires pulled up into the light assembly area, now we can go ahead and begin to make our connections here as well. Now on this side, were going to take an extra piece of white wire from the extra wire that we pulled up and we need to connect this to the white wire using a yellow butt connector so well double it up on one side. Well then put a small ring terminal on the other end and use a self-tapping screw and put the ground underneath the tail light assembly area somewhere where the body is doubled up.Now for the brown and green wire, well put a blue butt connector on the end of each of these. Well then go ahead and make our connection to the back side of the socket and bulb assembly and this time, the red wire will go to the green wire. The brown wire will go to the brown wire. Well be connecting the white wire with the black wire again for the ground. Once weve got all our connections made, again, well use some electrical tape to secure them as well as give them some extra protection. Now that everything is all taped up, we can go ahead and put the light assembly back into place.Again, to put the light assembly back into place, you just simply push the two tabs in towards the front of the vehicle and then line up the two extra holes that we removed the pushpin fasteners from. Now, were ready to go ahead and test out the lighting. Well do this by using the jumper lead that comes with the kit and plug into the four flat that we connected on the lower fascia of the vehicle. Well then connect it to our test light or if you dont have a test light, you can connect it to a vehicle that has a four flat coming off of it.First, well try the running light which is the brown wire. As you can see here, everything is working okay. Now for the left side, its the yellow wire. Thats for the left turn as well as the break. That seems to be working just fine as well. Now for the right side or the passengers side, it will be the green wire. Thats for the break and the turn signal as well. Again, thats working just fine. Now that weve done a test on all of our light functions, that will complete our insulation or the roadmaster tail light wiring kit with bulbs part number RM-155 on our 2014 Jeep Patriot. .

Found this item was wired with the brake lights for the brown wires and turn/running lights for colored wires and this fact kept me from getting this done very rapidly. Once identified, went together really nicely and actually grounded to frame for higher light output. I upgraded 3 wire into 2 wire converter with "Roadmaster Brite-lite 3 to 2 Wiring Converter" and they are as bright as the lights already in the housing. Except for that wiring issue, it would have been excellent. As to performance after install, great. Customer service was nice from Roadmaster as well. Did receive a call back message from etrailer a couple days later. 86819

Great idea. After years of towing with magnetic lights now all I have to do is plug it in, and I'm done. The kit kit comes with more parts and wire than I needed and was simple to install on my 2010 JK. 81930
Arrived in perfect condition and very quickly (3 Days) for reg. shipping. Thanks much. 59116

Very simple to install. I had plenty of room for another bulb. One downside was the 1inch hole they have you drill is not large enough for the bulb to go thru so I had to ream the hole a little. 88844

JUST A SHORT NOTE TO CONFIRM THAT I HAVE RECEIVED THE BASEPLATE AND WIREING HARNESS FOR MY TOW VEHICLE! THE SERVICE WAS FANTASTIC, AS WAS THE PRICE! I WILL DO BUSINESS WITH ETRAILER WHENEVER I NEED THE PRODUCTS YOU SELL. THANKS AGAIN KENNY 7532
Works as advertized. Easy install...just make sure you have 2 inches between your exsisting bulb and the kit bulbs. Not enough wire though....I had to go buy a 6' lenght to run from taillight to taillight. Hence the GOOD rating. 11557

enough wire to complete the job on a Wrangler, Followed the Blue Ox drill reccomendation from the mount plate and worked perfectly. Maybe a little pricie for what you get but its all together. 84968

On the 2014 jeep wrangled, the lenses are one piece sealed so there isn't a good way to drill the hole because if you make it big enough for the bulb to fit through, the socket is loose. 136722

Hard to install on 2013 Jeep Grand Cherokee as it is very difficult to determine where to drill so you have clearance and don't drill in to something vital. 103638
