Question:

The wires I use on my current configuration the blue ox coiled blue wire uses round plugs from coach to vehicle. This and all other wiring Ive found have flat blade. What can I do to rectify this?

Expert Reply:

If the coach uses the 7-Way RV style connector with blade style pins then you can use coiled adapter, # HM47065, with the Hopkins Custom Tail Light Wiring Kit, # HM56000, or similar tow bar wiring that has a 4-Way flat end.

If the coach has a 7-Way round pin connector then you can use an adapter such as # 47405. But you will likely need a 4-Way extension, # HM47115, to reach from the front of the vehicle to the coach.

If your coach has a 6-Way round pin connector then you would use an adapter such as # PK12717 along with the 4-Way extension listed above. I have also included a helpful link to our series of articles on tow bar wiring for you.
