Perfect replacement for Roadmaster four prong trailer connector. Decent quality and great price. Quick shipping.



- RM-910030-2

This plug seems to be of decent quality. I was unable to use though as the 4 pin socket I bought is incompatible. I was (falsely it turns out) under the impression that a round 4 pin was a round 4 pin. The Pollak PK11404 receptacle has 1 pin of one size and the other 3 pins slightly larger. Just an FYI.

  • Is There a 4 Round to 7 Round Adapter
    We have a possible solution for you but there is no such thing as a 4-round to 7-round adapter; you would need to make your own. What you could do is use the Custer Trailer Connector Adapter - 4-Way Flat to 7-Way Round # KIT-7P-4, cut off the 4-way flat and wire in the RoadMaster 4-Wire Connector # RM-910030-2.

    The wiring for the male connector is the upper right (3 position) is Left Turn and Stop, Lower Right (1 Position) Ground, Lower Left (2 position) Tailights, and Upper Left (4 position) Right Turn and Stop.

  • Connecting Roadmaster Sterling Tow Bar Wiring Extension To Jeep with 4-Pin Round Connector
    I have a solution for you, but we do not have a pre-wired adapter to allow you to connect the 6-pin round plug from the tow bar to a 4-pin round plug on your Jeep. One solution is to replace the 4-pin round connector on your jeep with a 6-pin round socket, # RM-910030-7. The Sterling Tow Bar # RM-576 includes a 6-pin round socket that will work well to replace the 4-pin round socket on your Jeep. You can remove the wires from the 4-pin connector, taking the connector apart with a small...
