The STRONGEST BEASTS ADAPT: Give your rig the ability to light up any trailer, 5th wheel, camper, UHAUL, or lighting accessory that uses a 4-pin connected instead of the standard 7-pin socket. The OPT7 7-pin to 4-pin adapter works with any factory OEM 7-pin plug for Chevrolet, for Ford, for Dodge, for RAM, or for GMC.
DRIVE ASSURED: Slides perfectly into any OEM 7-pin plug and stays on tight with resilient retainer fins. These fins work with your 7-pin dust cover to secure your adapter in place. No wiggle-room, no loose fittings. You can rely on your rear lights working 100% of the time.
READY FOR ANY SITUATION: Whether its a drive to the lake, or a day at the sun, the rust resistant prongs and heavy duty construction can handle whatever you throw at it.
