MECMO's 7-way RV trailer light connector is a prewired, heavy-duty vehicle-side 7-pin socket kit that delivers full lighting, brake, reverse and auxiliary power for trailers and RVs.

If you tow trailers, campers, or work with commercial rigs, a reliable 7-way connection is essential to transfer lighting signals, electric brake control, and 12V auxiliary power. The MECMO 7-way socket arrives as a ready-to-install pigtail harness with a mounting bracket, color-coded wires, and corrosion-resistant components so you can hardwire it into your truck or tow vehicle quickly and securely.

How does this connector handle all seven trailer functions?

The MECMO 7-way follows the RV-style 7-blade standard and routes separate circuits for taillights, turn signals, brake lights, reverse lights, electric brakes and 12V auxiliary power. Each function is accessible through dedicated, color-coded wires for straightforward identification during installation.
