4x4AT stock a range of tow bar electrics for the SsangYong Musso, both 7-pin and 13-pin. The 7-pin type plug has fewer options than the 13-pin – which are the basic legal and safety requirements of brake lights and direction indicators. A 13-pin allows for more wiring connections such as fog and reversing lights. We offer a professional fitting service for all the SsangYong Musso accessories we sell, available at one of our UK installation centres, contact us for details.
