To being with, we're going to go ahead and open up the hood of the vehicle. We're going to cut one end of the four flat off. We will not need this in this application. Next we're going to route our wire through the grill and through the engine compartment. It's a good idea to keep a couple extra feet up near the front of the vehicle in case if you have to replace a plug or move the location where your plug may attach to your vehicle.
Next we'll take the long strand of wire that comes with the kit, that has two ends of the four flat on it. The shorter wire is for jumping between your tow vehicle and your towed vehicle. In this case, we're going to route it behind the grill and then route it up into the engine compartment, following along some factory wires. We'll use some zip ties along the way to help secure it. Now when routing your wire, make sure you stay away from any moving parts, parts that may become hot, or sharp edges. Now that we've got our wire routed through the engine compartment, we'll fish it down towards the underside of the vehicle up near the firewall.
Now we'll go underneath the vehicle and route the wire back to the back end. We're going to end up back near the driver's side taillight at the rear of the vehicle. Again, we'll use some zip ties along the way to help secure it. Now that we're at the rear of the vehicle, we need to pull the plastic section of mud flap or under-body carriage that protects the wiring for both the taillights. We will not be tying into any of the factory wiring, but our wires from the bulb kit will actually be coming out right next to where our factory wiring is already at. Now that we've got our wires run to the back of the vehicle, we're going to strip the wire and we're going to keep the green wire solid and cut off the excess brown, white, and yellow wire.
The yellow wire will stay over at the driver's side. This will be the turn and brake signal for this side. We're going to need to make a jumper wire for the white and brown, so what we'll do is we'll use the excess wire and put it with our green wire that runs over to the passenger side. When routing this, we went ahead and used about five or six feet of half inch wire loom, which you can purchase by the foot, and it's part number 459075-1. Now on the driver's side, that should leave us the yellow, a brown, a white. The extra jumper wire that we carried over on the passenger side now, we should have a brown, a green and a white wire.
You'll also have the jumper wire over on the driver's side coming from the passenger that will be the excess brown and white wire that we ran over. This is how we'll tie our passenger and driver's side lighting together for the running as well as the ground. Now we'll take the covers off the taillight assemblies. We need to choose a location that we can drill a one inch hole so we can insert our bulb. Before drilling your one inch hole, you want to make sure that there's nothing behind it that can be damaged and you also want to put a pilot hole to check to make sure everything will clear. With our pilot hole drilled, we'll use the one inch hole saw. Now that we have our hole drilled, we'll remove the three bolts that hold the light assembly to the body. With this off, we need to take the light assembly and we'll need to bend the tabs out just a little bit so that we get a nice snug fit into the back of the light. A quick tech tip, it's a good idea when messing with any of the light sockets to take the bulb out so you do not damage the bulb. Now that we have our tabs bent out on the light socket and it fits firmly into place, before we put it in, we're going to strip a little wire off of each of the brown, the red and the black wire. Now that we have the light socket pushed into the back of the light assembly, we're going to use a little bit of silicone gasket maker to help seal it off and make sure no water gets into it. This is part number LT37467. We'll feed the three wires from the light socket through the hole that we drilled in the body and put the whole light assembly back on the body by putting the three screws that we removed earlier back on. We'll repeat the same process over here on the passenger side. With both of our light sockets installed in the light assemblies, now we're ready to do the wiring. Over here on the passenger side, we'll connect the green wire with the red wire using a butt connector, the black wire with the white wire using a butt connector, and the brown wire with the brown. Once these connections are made, we'll tape them up with some electrical tape. We'll also use a couple zip ties to help secure the wire. With that done, we can put the under-body panel back up into place and put the push pin fastener back in. Now we'll move over here to the driver's side. We'll connect three white wires, in this case we had to take an extra piece of the white wire that we had already cut off, as we'll need to use this as our ground wire. On this side, since we brought a jumper over from the passenger side, we're going to connect two of the brown wires together so we'll use the larger butt connectors, which are yellow in this case. For our yellow wire, we'll strip that back and put a butt connector on it as well. We'll make the connections with the back of the light socket. On this case, the yellow will go with the red, the brown will go with the brown and the white will go with the black. With all these connections made, we'll put some electrical tape on them as well. For the white wire that we brought down for our ground, we'll put a ring terminal on this one. We'll put some electrical tape on them as well. Now that we've got that done, we can put the under-body panel back up into place and put the push pin fastener back in as well. We're going to use the ground wire and use a self tamping screw and connect it to the frame of the vehicle. Now that our ground wire is in place, we're ready to test out our function of our lights. As you can see here, the running lights as well as the brake and turn are all working fine. Back on the front of our vehicle, we'll do a test as well as securing the four flat up into the grill area. As you can see here, if you use the jumper wire that comes with the kit to go from your towed vehicle to your tow vehicle, you just connect the four flat and then you connect to the back of your tow vehicle. When not in use, you can connect it back into the grill area. In this case, we just use a simple zip tie. Like I said earlier, it's a good idea to keep a couple extra feet of wire up behind the grill here, or up in the engine compartment area in case you ever need to replace this plug on the end. That will conclude the installation of our Road Master Taillight Wiring Kit with bulbs, part number RM-155 on our 1998 Jeep Wrangler. .

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

I ordered tow light kit RM155 for my Jeep Wrangler so we can tow it behind the motorhome. The kit was shipped imeadiately after my order was placed,and was at my doorstep within 5 working days. The installation was easy,the instructions were easy to follow. I couldn't be happier with the Quality and service. 104785
Good instructions. Everything need is included for 4flat connections. One bulb socket arrived with the ground (black) wire loose in the bag. The solder joint had failed. Resoldered but had to remove the other wires and rubber insert from the bulb socket to avoid melting. Not a shining example for Roadmaster. 147006

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
