How To Make a Trailer Wiring Harness Adapter with Two Vehicle Side Trailer Connectors

Question:

Hi, I found you have a 4 pole flat male to 4 pole flat male wire harness adapter. Do you have the opposite, 4 pole flat female to 4 pole flat female? I think I could use a 1 male to 2 female Y adapter, but that is not as clean solution. Thanks.

In order to obtain a trailer wiring harness with two vehicle side trailer connectors you will need to either splice two of the Hopkins Wiring Harness with 4-Pole Flat Trailer Connector part # HM48035 into one another with the Deka Heat Shrink Butt Connector part # DW05744-5 or you could just install the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector part # HM48190 onto the opposite end.

Unfortunately, we do not have a complete trailer wiring harness like the Roadmaster Extension Loop for Towed Vehicles part # RM-300150-00 with two vehicle side trailer connectors so you will need to make your own.
