Universal Wiring Harness

The Hayes Universal Wiring Harness is designed to be spliced into your vehicle’s wiring on one end and can easily be plugged or unplugged from your Hayes brake controller on the other end.

A few months ago we read about the 'SWAY MASTER" system, purchased one, and after a ten minute installation, have notice a big difference in the camper's behavior. This has involved only short trips until Summer and we are looking forward to the interstate experience.

We own a 2014, 34' Scamper pull behind camper, utilizing a 2013 Chevrolet Avalanche for towing.

“On a scale of 1 to 10, I rate the trailer braking performance of the Hayes G2 Brake Boss a 10. I particularly like the larger size and better location of the manual activation lever. It’s easy to find without looking down for it. After becoming familiar with the functions of the 3 adjustments buttons they provide an easy way to set up and review settings and also diagnose problems.”
