Not all trailer couplers and vehicle hitches are the same height; due to this, some vehicles will require extra length on the trailer wiring to plug in to the tow vehicle and provide enough slack for turning radius. The Hopkins Towing Solutions Flex-Coil 7 RV Blade to 4-Wire Flat Adapter with Nite Glow provides this extra reach while ensuring that the wire will not drag due to the Flex-Coil design. Nite-Glow connectors illuminate upon the activation of the taillight function to verify electrical continuity between the vehicle and the trailer. This adapter also features increased weatherproofing to ensure that it functions properly in all conditions. With tin-plated terminals and easy-grip connectors, it is easy to use this 7 RV blade to 4-wire flat adapter.
