Review of Roadmaster Tow Bar Wiring RM-155

Today we're going to be taking a look at part number RM-155. This is the road master taillight wiring kit with the included sockets and bulbs. This kit is going to let you use your toed vehicles, brake, running and signal lights without taping into the vehicle wiring. Please note, to get this installed your toed vehicle must have enough room inside the tail light lens housing for an extra bulb and socket assembly. The size hold that you're going to need in order to get the socket mounted in the taillight housing is going to be one inch in diameter. You can use a one inch hole saw or a rotary cutting tool to make that hole. When you're installing this your wiring is going to be routed beneath the vehicle.

It's going to come with the protective wire loom, you're going to get three feet of this loom to protect certain areas of the wiring from sharp edges. All you have to do is simply cut the length that you need and fit if over your wires to protect the wiring from those sharp areas. This unit does maintain the manufacturers warranty on toed vehicles by avoiding any involvement, whether it's a logical system, the overall measurement of the bold measuring from the very base to here at the end of the lens, that's going to give us a measurement of about two in one quarter of an inch. Measuring from the flanks to the top of the bulb is going to be about two inches and the bulb type that this system uses 1157. It's going to include all the necessary wiring. You're going to get a harness right here, this is going to be 30 feet long, it's got the dust caps on the connectors and this is going to be your female connectors on both sides.

You're going to get the 30 feet long wiring. You're also going to get the six foot long wiring, again wiring connectors. They're going to be your main lenses, it's going to be the hardest it runs in between the back of the RV and the toed vehicle. You're going to get three feet of half inch split loom, you're going to get the two lights and the sockets, you're going to have about eight inches of wiring coming out the back of the sockets, you're going to get all necessary connectors. You're going to get the blue connectors for single wire connections, these are your butt connectors. You're going to get yellow butt connectors for two wire connections and you're going to get a small ring terminal to make your ground connection.

You're going to get zip ties to tidy up any wires underneath the vehicle and you're going to get the included instructions. These are going to walk you through the installation process step by step. The kit is made in the USA. Now when it comes to the installation you will need to gain access to the back of both taillight assemblies. You're going to need to find a suitable location to mount the bulb and socket inside the tail light housings. The bulb socket must be installed underneath red lenses and it must at least be a quarter inch clear between the bulbs and the lenses.

You'll need to drill out that one end circular hole through the back of the taillight housings. Right here around the flange it's going to have spring loaded taps that encircle the socket, you'll need to bend those outward slightly, snap the bulb into the hole that you just drilled and that's going to provide the nice tight fit that we need to make sure these don't vibrate loose and come out of the taillight housing. Then you're going to need to attach one end of the 30 foot harness at the front of the vehicle for connecting the URV, at the other end of the 30 foot harness you can cut off the connector. This is going to be the end that's going to run to the back of the vehicle, that's the taillight assemblies for connecting the end of the bulb and socket wiring. Again you're going to route the wiring beneath the vehicle and you can use the included zip tires just to straight the wires up and out of the way. Then you would use the included butt connectors to attach the electrical harness to the taillights, you will need to reinstall everything, make your ground connection and clean up your installation and then you're going to be ready to connect your six foot wiring harness between the plug at the front end of the vehicle and the back of your URV. Again, instructions are included, very detailed, they're going to walk you through the entire installation process step by step. That's going to do it for our review of part number RM-155. This is the road master taillight wiring kit with the bulb and sockets.
