• Recommended Replacement Molded 7-way Trailer Plug and Cord
  The Epicord # 277-000143 7-way plug you'd looked at would indeed make a better connection than something like the # H20044 that just has the single contact. Keep in mind, the wire color coding on this plug/harness might be different than what you already have, so be sure to look at the chart on the # 277-000143 product page that lists the wire colors and their purpose.

• Troubleshooting Trailer Wiring Install Where Blinkers Activate Both Sides of Trailer
  Sounds like you might have swapped the turn signal circuits and the running light circuit on your trailer wiring. This would cause both of the blinkers to flash when you put on either blinker. So what I would recommend you do is start over with the wiring connects. Use a jumper wire from a 12 volt battery positive post to run voltage to each of the trailer wiring circuits so that you can identify what all of the circuits are. And then use the diagram you found already to make the connections...

• Parts Needed to Replace Trailer Connector on 2018 Rockwood A122s Pop Up Camper
  I have a solution for you, but there is not a "plug and play" type wiring solution available for this so you would need to cut your existing wires.

If you wanted to go with something slightly shorter, like the # 277-000143 that you were looking at, you can use that 7 way and add the Junction Box # 3375601101...

• Parts Needed To Install 7 Way Plug on Trailer
  Since a 4 way connection does not provide you with the capabilities to control the trailer's brakes, you would need to convert your boat's 4 way connector into a 7 way using something like the Epicord # 277-000143. In order to make wiring a bit easier and more organized, I also recommend using a Junction Box like the # 38656 so that you can connect all of the trailer wires to the box and then neatly wire the Epicord to the box. This will help ensure that all of your wiring is cleanly installed...

• Why Do Some 7-way Plugs Use Dual Contact Surfaces

Both types are compatible with each other. The Bargman...

• Troubleshooting Trailer 7-Way Plug that Wants to Disconnect from Vehicle Connector
  The standard 7-way trailer connectors have always had the same diameter. There isn't a smaller diameter size that's out there that your trailer would have and be causing the problems you mentioned. Most likely your best solution is to replace the 7-way plug on your trailer like with the plug and lead part # 277-000143. Or for just the plug you could use the part # PK12706 and you'd be good.

• Brakes, Hubs, and 7-Way Plug for Viking Popup Camper
  We can most likely help with what you need but we need more info from you to pick out what you need. For hub/drum replacements I need to get the bearing numbers from your old hubs or the dimensions of the spindle on your trailer axle. From there we will be able to determine which brake assemblies you'd need. Then for wheel and tires I need the bolt pattern of your wheels and the tire size that's on the sidewall as well. Do you have a 4-way or a 7-way connector?

• Can 7-Way and 4-Way Both Install on Trailer for Separate Wiring Circuits
  When you say rear lights do you mean like utility lights so that you could see in the dark? If so you could just use the 12 volt accessory circuit of the 7-way to accomplish that. But aside from that you certainly could have two different connectors on your trailer for two different sets of lights. For a 7-way plug all you'd need is the part # 277-000143 and then for a 4-way part # A25W2GWB for 25 feet.
