Choosing the correct connector for my pop-up camper and F 150 baffled me before I asked etrailer for help. I got that help, bought the etrailer connector, and it worked like a charm. The lube that came with the connector was an unexpected bonus. Many thanks.

  • Adapter to go From 6-Way Round Connector to 4-Way Flat

  • Part Recommendations For Flat-Towing A 2006 Hummer H3
    In order to be able to flat-tow your 2006 Hummer H3, there are 5 items needed. You will need base plates for the Hummer, a tow bar, safety cables, lighting for the H3, and most states now require a supplemental brake system. The base plates I recommend are the Roadmaster Base Plates, part # 2505-3. When the front arms are removed the system is virtually invisible. The tow bar I recommend is the Roadmaster Falcon 2 Tow Bar, part # RM-520. This tow bar has a weight capacity of 6,000...

  • Will the Hopkins Endurance Flex Trailer Connector Adapter # HM47320 work on a Harley Trike
    What matters more than wire color on the 6 way on your Harley trike is circuit location. Judging by the list you gave me it looks like the 1 circuit (ground) is in the 3:00 position of the plug and the circuits after that go around the connector counter-clockwise and end with the center pin. Check out the picture I attached to see if your connector is wired up like the standard 6-way wiring. If so, then yes the Hopkins Endurance Flex Trailer Connector Adapter # HM47320 that you referenced...

  • Parts Needed to Make a Taillight Signal Converter to Go From 6-Way Separate to 4-Way Combined
    Since your tow vehicle has separate turn signals and it sounds like your trailer has combined signals you will need to use an converter like the # RM-732.

You will want to determine the pin outs of the 6-way of your trike so you know how to wire up the # PK11604. Use a circuit tester like part # PTW2993 for this. You will want to...

    Since your truck has a 4-Way flat connector and the trailer has a 6-Way round, adapter # HM47320 will not work. It is made to go from a 6-Way round on a vehicle to a 4-Way flat on a trailer.

The other two wires on the adapter are black for 12 volt power and blue for electric brakes. If you do not wish to use these functions then you can tape...
