With the socket removed, you will then just need to route the wiring through the housing, and then secure them ot the socket terminals. After securing the...

• How to Wire Nissan Tow Car to Winnebago Motorhome with 4 Pin Round Connector
  Wire colors on motor homes and vehicles are not standard and vary, even between models produced in the same model year.

Use the circuit tester and have someone in the vehicle activate each function. Once each function is located on the car and motor home label each one...

• Will the Roadmaster FuseMaster Fuse Bypass Fit a 2011 Ford Edge
  Yes, the Roadmaster FuseMaster Fuse Bypass, # RM76511, will work on your 2011 Ford Edge.

These wiring kits connect inline with your tail light wiring at the tail light assemblies and provide...

• Different 4-Way Connector Styles and Adapters
  There are not two different 4-pin round connectors; there are just two types of 4-pin connectors, 4-flat such as the Hopkins Endurance 4-Way Flat Trailer Connector # HM48110 and 4-round such as the Pollak Heavy-Duty, 4-Pole, Round Pin Trailer Wiring Connector # PK11402.

• 4-Way Round Trailer Connector for 12 Volt Trailer Wiring Circuit
  For a 4-way round plug we have the part # PK11402 and then for a matching socket part # PK11410 which would work great if you wanted to use it for connecting to a 12 volt battery. Since this is an alternative use for this type of connector you really don't have to use any specific wire of either connector and would have freedom to pick which ever. For carrying a higher amperage you could use the 10 gauge wire part # 10-1-1 which we offer by the foot.

• What is the Wire Gauge Used in Hopkins Heavy-Duty Trailer Coiled Extension - 4-Pole Round
  The Hopkins Coiled Extensions with the Nite-Blow such as # HM47045 use 16 gauge wires on the inside. Trailer wiring harnesses usually use 16 to 18 gauge wire for lighting functions and heavier wire for components that draw more amperage. On a 4-Way, you should have left and right turn signals/brake lights, running lights, and a ground so 16 gauge wire will work fine. But if it is for something other than lights then you would likely need to make an extension. We have jacketed 4-wire, #...
