Deolenoom 7‑Pin Trailer Wiring Harness Kit — 7‑Way + 4‑Flat Connector, Weatherproof Bracket & Corrosion‑Resistant Terminals

The Deolenoom Towing Solutions Vehicle Wiring Kit is a complete 7‑pin (7‑way) plus 4‑flat trailer connector kit that lets you power lights and electric brakes on trailers from Ford, GM, Chevy and most trucks.

This wiring kit is built to replace worn or corroded trailer connectors, add a factory‑style 7‑way connection to your truck bed, or provide a multi‑connector solution for towing trailers with different plugs. The kit includes a 7‑way wiring harness with weatherproofing, a bracket that holds both a 7‑blade and a 4‑flat connector, pre‑greased phosphor bronze terminals, and basic mounting hardware for a straightforward install. Materials and construction aim to resist rust and abrasion while maintaining reliable electrical contact for trailer lights, reverse power, running lamps and electric brakes.

How does this kit connect to my truck and trailer?

The Deolenoom kit supplies a 7‑way harness that taps into your vehicle wiring and presents both a 7‑blade RV style and a 4‑flat trailer plug on a single bracket. Install requires mounting the bracket to the hitch area and wiring the harness to the truck’s tail light circuits and ground. The pre‑greased terminals and weatherproof covers simplify assembly and extend service life in outdoor conditions.

• Includes a 7‑way wiring harness with flexible protective sleeve
• Bracket mounts both 7‑blade and 4‑flat connectors together
• Pre‑greased phosphor bronze terminals reduce corrosion

The kit is designed for use with Ford, GM, Chevrolet, GMC, Ram, Nissan, Toyota, Dodge and similar trucks, and supports trailers that use standard 7‑way RV blades or 4‑flat connectors. Always verify wiring pinouts on vehicle and trailer before wiring to avoid mismatched functions.

These features reduce the chance of intermittent signals and dashboard warnings about trailer wiring.
