7 Way Trailer Wiring Harness 4 Way Flat Plug For Ford F-150 F-250 F350 1999-2024

About this item

This is a direct-fit wiring adapter (SI-70206042) that plugs into your Ford's factory USCAR tow connector and gives you both a 7-way RV blade socket and a 4-way flat trailer plug. No wire splicing or cutting needed — it simply connects to the OEM tail light harness. The rubber housing resists rust, the slit loom protects the wiring, and a spring-loaded cap keeps the plug clean between uses. Works only on USCAR-equipped vehicles with a factory tow plug — check your truck's connector before ordering.

• Adapter converts your truck's factory USCAR 7-pin plug into a 7-way RV blade socket plus a 4-way flat connector
• Plug-and-play design — connects straight to the factory tail light harness, no cutting or splicing
• Spring-loaded dust cap keeps the socket clean when you're not towing
• Wires run through a protective slit loom sleeve for durability
• Housing is molded from black rubber that resists rust and corrosion
• Fits Ford F-150 (1997-2024), F-250/F-350/F-450/F-550 Super Duty (1999-2024) with factory USCAR tow plug and OEM tail light connector
