Video Transcript for Roadmaster Wiring - Trailer Connectors - RM-910030-1 Review

Today, we're going to take a look at the Roadmaster 4-wire vehicle end trailer connector. Now, this connector will install in the vehicle that's being towed to allow you to plug in a 4-pin plug from the tow vehicle. This replacement socket will fit the Roadmaster 4-wire straight and the Flexo-Coil electric cords. Includes this nice spring-loaded cap that will automatically drop down to cover the connector when it's not in use. And to install your wire to this, you just run your wire back through here, make your connections to the 4-pin, and you're ready to go. Just to show you where those connections are made, to do it, you just take out this little Phillips head screw and once that screw comes out then just open the cover or the plate and then just tap it and you'll see the center comes out and there's your 4-pin. And on the very back is where you'll make your wire connections.

So, just run your wire through here, bring it out, make your connections, and then all you have to do is slide this right back in. Make sure the hole at the top lines up correctly. Once you get that hole to line up, then go ahead and take your . Let's get the little Phillips head screw. Once we get that put on the screwdriver ...

There we go . And just line it up with the hole and go ahead and tighten it back down. Then once you get it all tightened down it's secure and ready to go. Then you're all ready to plug in your connector. That should do it for the review on the Roadmaster 4-wire vehicle end trailer connector.

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. 168236

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-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...

  • 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.

  • 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.

  • 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. Since we don't have any plug and play tow bar lighting kits the best option is...
