Review on 🚗 CURT 56225 Vehicle-Side Custom 4-Pin Trailer Wiring Harness for Nissan Frontier, Pathfinder, Xterra & Suzuki Equator by David Elam

This wiring harness is very easy to install. The enclosed instructions refer to the particular vehicle for which it is suitable. The hardest part was removing the protective caps under the truck body. But after that no problem. Just take your time and pull evenly on the trim pieces on the inside to avoid tearing them. The open plug is easy to find (points to it in the picture). There are enough cables from the truck to the trailer. And there's plenty of room to stow a relay behind a wiring harness in a truck.
