Adding a New 7-Way Trailer Connector and Wiring to a Car Hauler Trailer


Hi,i was looking at this HM20087 to rewire my car hauler. Question:How do you recommend rewiring to the back lights and side marker lights? Is there a kit to rewire complete trailer? Thanks


Expert Reply:

You will likely need some additional wire to reach the lights when installing 7-Way connector # HM20087. If you just want 4-wire you can use # DW04923-1, sold by the foot, or # 16-4B-1, also sold by the foot. You will also need some butt connectors such as heat shrink version # DW05744-5. If you want all 7-wires you can use # DW04914-1 which is sold by the foot as well.

Another option is a 7-Way that is considerably longer, # 50-67-008, which at 22 feet long is more than twice the length of the one you referenced. With it you may or may not need additional wire (though you will likely need a jumper wire for the running lights to go from one side of the trailer to the other).

There isn't a kit because trailers come in some many different configurations and lengths there would have to be a lot of kits.
