Video Transcript for Trailer Wiring Harness Installation - 2014 Honda CR-V

Today in our 2014 Honda CRV, well be installing the Roadmaster Tow Bar Wiring Kit with bulb and socket, part number RM-155. To begin our install, well first need to remove the tail light assemblies. To remove the tail light assemblies, well open up the rear hatch and then remove the two fasteners that secure the tail light assembly to the body. Next, well go ahead and gently remove the tail light assembly from its position releasing the fasteners and being careful not to break the alignment tabs underneath. When the tail light assembly is pulled out, we can see the back of the tail light assemblies where well mount the bulb and socket.To mount the bulb and socket well first need to drill a hole under the back of the tail light assembly as per the instructions. Well use a 1-inch hole saw.

Now the hole drilled out, well need to fit the bulb and socket through our hole. The small tabs that go around the socket itself are flexible so that we can bend them as necessary for nice secure fit into our hole. Well go and bend them out as necessary and then fit the socket to our hole. For this application because the surface is not completely flat, well also use an additional sealer to help hold the socket in position.Well be using the Loctite RTV, part number LT37467. Well go ahead and put the RTV around the socket and then the socket into the hole.

Quick tip, to help prevent the sealant from getting on the bulb, I recommend to apply the sealer to the socket assembly and then install the socket assembly into the back of the tail light lens. Well take a zip tie and secure the tail light socket to the manufacturers wiring. Well cut the excess from zip tie and repeat the same process on the other side. Next, well get underneath the vehicle and go ahead route our 4-pole harness right behind the tail light assembly.Well raise our wiring to the bulb and socket kit to our 4-pole harness. Starting on the passenger side, well go ahead and cut off one end of the 4-pole harness.

We can go ahead and throw it away as it will not be used in this application. Then well go ahead and peel back the wires and start stripping it back. Note, well cut off the yellow wire short cause it will not be used here on the passenger side. Well go ahead and add the blue butt connectors and secure them. Well then being matching up with the bulb and socket wire.

Well match green to red, brown to brown and white to black.I recommend to wrap them up with some black electrical tape to help keep out any dirt, dust, debris or moisture. Well go ahead and secure the wiring as necessary, cut of the excess from our zip tie to clear up our install look and then reinstall the tail light assembly. Next well get underneath our vehicle and go ahead and route our 4-pole harness over to the drivers side and up behind the drivers side tail light assembly. This application maybe necessary to use a pull wire to assist in routing the wire. Pull wire can be a stiff piece of wire or in this case a piece of air tubing that we use to assist in routing up our new 4-pole harness.Once we have the pull wire in place, we can then tape our 4-pole harness to the pull wire with some black electrical tape and then pull it into position. Now, we have our 4-pole harness up behind the drivers side tail light assembly. Well go ahead and cut the white brown and yellow wiring in half. Well peel back both sides and strip them back. Well then take the two-inch that we just cut, twist them together and secure them to one side of the yellow butt connector. The other side, well match up with the tail light socket that we installed here in the drivers side. Itll be a brown to brown and red to yellow.Now, here on the drivers side before we connect the black wire to the white wire for our ground, well add an additional piece of white wire that can be taken off the 4-pole harness to our black wire. Twist it together and then connect it to the white wire that we ran over from the passenger side. Well take the other end of our additional white wire that were adding, cut off any excess, strip it back and add the blue ring terminal provided with our install kit. Well use a self-tapping screw to make this connection. Note, I recommend to find an area where the sheet metal doubles up for more secure ground.Here behind the tail light assembly is a good location. With the ground secured, well go ahead and wrap up our wires with some black electrical tape. Then well take the 4-pole harness and route it back down underneath the vehicle. With our wires routed, well go ahead and secure them as necessary and cut off the excess from the zip ties to clean up our install look. Next, we can go ahead and reinstall the drivers side tail light assembly. With that done, well back underneath the vehicle and start routing our new 4-pole harness up to the front of the vehicle and ultimately to our base plate bar.Keep in mind were routing our wires with many moving components such as steering or suspension or excessive heat such as exhaust. As we route the wire well also secure it with some zip ties as necessary. For this application it may also be necessary to loosen or remove some of the underbody panels when routing your wire. With the wire routed and secured well go ahead and mount it to the base plate using the hardware provided with the base plate. Well go ahead and secure the mount with self-tapping screw directly to the base plate electrical mount then well go ahead and route the 4-pole to it and secure it with a zip tie.Next, well take any excess wire from our 4-pole harness and secure it to the backside of the base plate. Now the wiring is secured, well go ahead and clean up our install look and this will complete the install of the Roadmaster Tow Bar Wiring Kit with bulb and socket part number RM-155 in conjunction with the Loctite RTV part number LT37467 on our 2014 Honda CRV. .

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

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


Comments

I had the same problem with the 1 hole saw that I used. After measuring with a micrometer, I found that the bulb is about .975 and the hole saw was only about .955. I reamed the hole with a 1 spade bit and the bulb went right in.

  • Why is RoadMaster Tail Light Wiring Kit # RM-155 Not Recommended For a 2011 Chevrolet Malibu LT
  • Neither one of our manufacturers, RoadMaster or Blue Ox, recommend to use the bulb and socket type of lighting when flat towing a 2011 Chevrolet Mailbu LT. Usually it is because of limited space in the taillight housing that does not allow the bulb and socket to fit properly. We go by what the manufacturers recommend, since they have already done a test fit on the vehicle. The RoadMaster Diode Wiring Kit, part # RM-154, or the Blue Ox Wiring Kit, part # BX8848 is recommended for your Malibu.

  • Bad Ground Connection Prevents Roadmaster Bulb and Socket Kit RM-155 From Working Properly

Make sure that both bulb assemblies are grounded securely to clean bare metal on the vehicle frame. If the vehicle frame is undercoated, you will need to scrape a bit of it off so that the ring terminal on the ground wire gets direct contact with the frame member or chassis.
