Description

This plug-and-play wiring harness routes an extra 7-way RV blade connector socket into a pickup truck bed, while retaining power to the existing rear connector. It allows easy connection for 5th wheel or gooseneck wiring, handling tail, brake, reverse, turn signals, brakes, and auxiliary power. It's a 7' extension with right-angle plugs, a spring-loaded dust cover, and protected by a slit loom. This 10-pack requires a 2-1/8" hole saw for installation.
