Today on our 1998 Jeep Wrangler, we'll be installing the Road Master Taillight Wiring Kit with bulbs, part number RM-155. 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. .

Use your towed car's signal lights without tapping into its wiring. This self-contained wiring kit bypasses your vehicle's electrical system, eliminating any concerns over violating the manufacturer's warranty.Went pretty easy. Holes for bulbs do fit in the rear lights. I had to use a 6way plug that had a 4way line on it also.
Always completely satisfied with Etrailer service and products! Jamie B is very knowledgable and courteous!
This was a good option for our 2020 Chevy Equinox because it does not tie into the tow vehicle electrical system and runs directly from the Motorhome electrical system.
Put this into a 2002 Jeep Liberty. Good directions. Drilled out the lower part of tail light housing and install bulb sockets into it. You may have to deburr the tail light housing a bit and manipulate the tangs on the bulb socket but is fine. I put in 1157 LED bulbs :) Good stuff!
This product was easy to install but it took some time routing the wiring harness from the front bumper to the rear. Pick up some extra zip ties, you will need several. The lighting system is independent allowing for the use of LED bulbs. Great product.
easy install one year later still working perfectly
it worked well
very well made and packaged
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.
I purchased a Blue Ox base plate, Air Force One braking system, and a light kit for my 2013 Durango. I could have not asked for an easier process with selecting and ordering, also the tutorials and videos were a great help in determining what was the best system for me . Everything arrived as planned and in great condition. This is not my first time using etrailer.com and my prior experience was equally good.

After using the items I reviewed, about 6,000 miles, I am more than satisfied. The towing setup is easy to hook up and unhook and the braking system is second to none. All of the installation was completed by myself and a friend, both of us have a technical background him more than me and we found the videos of the installation extremely helpful.Thank you for following up and providing excellent products as well as support services.
Great customer service fast delivery and reasonable price. Been purchasing from ETrailer for years
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.

Thanks Patrick. It works so well I forgot I had it.
I like this product and would definitely buy it again. I like not having to splice into the vehicle wiring and install diodes, etc. It is a clean installation with good instructions. All I have to do to hook up the lights is raise the hood of the towed car and pull out the pigtail and hook it to the motorhome. It is powered by the motorhome and does not run down the battery in the towed car. Great product.

Works great! Would definitely recommend it.
great kit i have installed them before
I have used the brake light wiring kit on 2 other towed vehicles. It is an easy install, does not compromise the original factory wiring and works well.

Easy install, working well 1 year later.
This kit really simplifies wiring tail lights on a vehicle that will be towed. No cutting into the vehicle's wiring and adding isolation diodes. Very functional and easy to install.

The parts are working perfectly. Thank you.
Kit was of good quality components. I would recommend about twice a much protective wire wrap along with extra of the smaller butt connectors. Fortunitely I had what I needed on hand. I also used a larger ring terminal.

Works great. 2002 Jeep Wrangler tail lights have plenty of room for the extra tail light bulbs.
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.

no issues, working as expected
Nice to not have to splice into vehicle wiring harness. Separate bulb assembly in existing tail light housing works great for towing our "TOAD" behind motor home.

Still works great after a year of towing to many destinations.
A very clever idea for an easy, neat, simple installation to safely operate tail lights on a towed vehicle. We installed this kit on our 2017 Chevy Sonic and it works great.

Thanks for the follow up. Everything is working just fine, no problems, nothing but good performance.
Great product, not a bad install and works great. I chose to cut off both 4 flat connectors and I installed a 4 round connector with spring cover on the front of my CRV. Looks and work out great.

Still working fine.
I really didn't want to install a separate bulb kit but our Equinox light was not compatible with our motor home. I was also installing a trailer lighting harness for the Equinox at the same time and doing them together made a lot of sense. I found this kit to be easy to manage and that drilling into the rear light housings not nearly as difficult as I had imagined. I would share a picture of the result but fortunately there is nothing to see - everything fit right into the Equinox's rear lamp structure. I compared the original lights with those from the kit driven by the RV and found them to be a great match. I upgraded the kit bulbs to LEDs for greater longevity.
I purchased this wiring kit for use in my 1999 Mazda Miata.
I did not want to cut into the OEM wiring harness, even using the diode method to safeguard the system. I felt that the fully separate wiring harness was more to my way of thinking for getting my car ready to tow.
I did not follow the included instructions that said to run the flat 4 wiring beneath the car, zip tying it along the way free of the exhaust and moving parts. I ran it through the firewall, beneath the dash, under the center console, and under the carpeting back into the trunk area. I then installed the bulb holders as instructed in my OEM Miata taillight fixtures.
I am happy to have all the wiring up and out of the way of potential road hazard damage, as well as the hot and/or moving parts beneath the car.
It works perfectly, and I am glad that I purchased this kit, and also that I decided to install it the way I felt best to do so.
It took much longer my way, but I'll never have to mess with it again.
This time it went without a hitch. last time was another thing. hopefully moving forward its all good.
thankyou
Watched video and installed with no issues. Great product! Will buy again for future vehicles.
