The MECMO Multi-Tow 4‑Way to 7‑Way adapter kit solves that by taking a factory 4‑pin flat vehicle socket and providing both a seven‑pin RV blade and an additional four‑pin flat output, plus an included mounting bracket, seals, and hardware for a tidy install.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter let me tow different trailers from the same vehicle?\u003c\/h3\u003e\n\n\u003cp\u003eThe adapter splits signals from a vehicle 4‑pin flat into two usable outputs: a full 7‑way RV blade to feed brake, turn, running lights, reverse and auxiliary 12V, and a separate 4‑way flat plug for simpler trailers.
