Question:

Im looking for a wiring harness for a gooseneck flatbed trailer that includes the wires that go to the running lights, brake/tail lights, brakes, ect. All I can find is the plug but not the actual wires that run to the lights and brakes. Maybe Im searching it wrong? Can you point me in the right direction? Thanks.

Hi Dan, and I believe you are looking for a 7-way with the wires connected such as the 4 foot long Hopkins 7-Way # H20043, 8 foot long # H20046, or 11 foot long # HM20048.

These have the plugs as well as wire leads that go to your junction box, though if you don't have a junction box you can also get that with part # 3375601101.

The actual wire itself is something you have to get separate, depending on the length you need. You order it by the foot: 16 gauge # 16-1-1, 14 gauge, # DW02422-1, 12 gauge, # 12-1-1, or 10 gauge # 10-1-1.
