The Uriah 4-Wire Bonded Trailer Wiring Harness is a dependable solution for rewiring your boat, utility, or snowmobile trailer. At 25 feet in length, this harness provides ample wire to reach the back of most standard-sized trailers, ensuring your taillights, turn signals, and brake lights are fully functional. The “bonded” design means the four individual wires are joined together into a single flat ribbon, which prevents tangling and makes it much easier to pull through trailer frames or secure along the rails. It is an essential kit for anyone looking to replace old, corroded wiring with a clean, reliable connection that meets DOT safety standards.

When installing this harness, it is a good idea to use plastic wire loom or heat-shrink tubing at points where the wire passes through holes in the metal frame to prevent the edges from rubbing through the insulation. To ensure your lights stay bright, sand the area where you attach the white ground wire down to bare metal before screwing it in. This prevents flickering lights caused by a weak ground connection through paint or rust.
