Video Transcript for RoadMaster 4-Wire Connector Installation - 2003 Honda Element

Today on this 2003 Honda Element, we're going to install part number RM-910030-1. This is a Road Master 4-wire connector. The first thing we need to do is go ahead and remove the original connector that's on our vehicle. In this case, it's a 4-pole flat, so we'll simply just cut off the end. Then we'll go ahead and take apart the 4-wire connector. We'll take out 1 screw in the top, and then push the insides out the front.

When we take it apart, we'll have the inside for the connectors, and a small soft plastic band. Now we'll take the outside part of the connector and push it over the wires, and push it pretty far back. Next, we'll go ahead and take the soft plastic ring and slide it on the wires as well. We'll use the lid to keep tension on the wiring and hold everything in place. Now we'll go ahead and strip back our wires. We'll go back about 1/4", and then twist the ends of the wires.

We'll go ahead and install our wires into the terminals on the inside. Loosen up the screws and they simply slide in. Starting on a pin on the left-hand side, on top, we'll install our yellow wire for the left turn. Across from that on the top will be our right turn. Looking from the outside in, we should make sure that we have our white wire on the left-hand side, and our brown wire on the right-hand side.

Okay, once we've double-checked everything, we'll go ahead and slide the plastic ring back over the connectors. Then we'll follow it up with some electrical tape. Then we'll push the whole assembly together and make sure that our screw hole on the inside part lines up with the screw hole on the outside part. Then we can go ahead and reinstall our screw. With that, our electrical connection is complete. Now we need to go ahead and install it to our base plate.

Now this base plate has 2 rods coming out from the center to hold an electrical connector. So we'll use those accompanying parts to help hold our 4-pole bracket in place, since this part number does not include any hardware to install it to any type of bracket. So we'll use existing hardware to make our connections, and then tighten it down for good. And with that our electrical connector is fully installed. And that will finish it for part number RM-910030-1 from Road Master, on our 2003 Honda Element. .

We just finished a makeover of our 1995 boat trailer. New bunks, sanded and painted but the best part of the project was the new LED lights from your company. They are so much brighter than the old incandescent bulbs that you really do feel safer driving down the road. We pulled the 20 year old wire out and replaced with new and used the 3M scotch loks to tie in. We were not sure the new style grommets would fit the old holes in the frame but they fit great. Your customer service was great, alerting me to a backordered reflector but recommended a replacement that worked fine. Patrick set up a Q&A page for me since I had questions about the best way to protect connections with dielectric grease, heat shrink and tape. Your website is one of the best with ease of navigation, complete pictures, great selection and thorough info, dimensions, etc. You guys really have your act together and also offer great value. I would not hesitate to purchase again and will recommend you when I can. I have attached a couple of pictures. Thanks for all your help. Wayne N.

Ask the Experts about this Roadmaster Wiring

  • Is a 7-Round to 4-Round Adapter for Trailer Lights Available?
    I can offer you a solution, though a 7-round to 4-round adapter is not available. What you will need to do is create your own by wiring a 7-round trailer end connector, # PK11700, and 4-round vehicle end connector, # RM-910030-1. I recommend going with the 14 gauge, Deka Jacketed 4-Wire, # DW04923-1, which is available per foot so you can get the amount you need. If you have an RV-style connector (which is often referred to as a 7-round), then the part you would be looking for is the...

  • 4-Pole Round Pin Trailer & Vehicle Connectors to Allow Conversion from 4-Pole Flat Connectors
    We offer trailer connectors, sockets and plugs in many connector formats that you can view in the linked article on trailer wiring. I also linked our main page for all 4-pin round connectors such as vehicle-side female socket # RM-910030-1 and trailer-side male plug # PK11402. We also have a kit with both, part # RM-910030-4 from Roadmaster. You'll want to be sure to wire the new connectors based on each wire's function, not by its wiring insulation color as this is not always consistent.

  • Best Tow Bar and Flat Towing Components for 2016 Jeep Wrangler
    Since you said you want the best and lightest weight tow bar for your flat towing setup the Roadmaster Nighthawk part # RM-676 is the way to go. It's about 20 lbs lighter than the competition, is very easy to use, and comes with safety cables and and an umbilical wire kit. The correct base plate kit you'll want that fits your 2016 Jeep Wrangler and this tow bar is the Direct Connect kit part # 1444-3.

  • 4-Way Flat Adapter Recommendation to Use with RoadMaster 4-Wire Connector # RM-910030-1
    Yes, the 4-way round to flat adapter part # ADP001 that you referenced will work with the RoadMaster 4-Wire Connector # RM-910030-1. It will plug right in and give you a 4-way flat to use.

  • 4-way Round Trailer Connector to 4-way Flat Connector
    I have a solution for you. However, we do not have an adapter to fit your 4-pin round connector on your trailer. Because of the rarity a 4-way round connector, I recommend either cutting off the 4-way round and attaching a 4-way flat, or splicing a 4-way flat into your wiring in addition to the 4-way round. To attach a 4-way flat, you can use part # HM48035. If you remove your 4-way Round connector, you will want to use butt connectors # DW05744-5. If you want to add the 4-way Flat...

  • What is the Center Bracket for In Roadmaster Base Plate Kit # 1425-1, 2004 Jeep Grand Cherokee
    You are correct. The center bracket with the round hole in Roadmaster XL Base Plate Kit, # 1425-1, is for the wiring harness to mount to. A connector like # RM-910030-1 can be mounted in that bracket, or Pollack connector, # PK11404.
