Designed to adapt our Trailer Light Testers to trailers that have a standard RV round 7-blade plug and cable attached. SAE 7-Pin plug — same configuration as all SAE 7-Pin sockets. Other end has an RV 7-Blade socket. Switch to RV wiring protocol made in adapter. Turn signal and brake light functions are combined, and the brake circuit now powers the RV trailer’s electric brakes. Solid brass pins/sockets.
