Hoppy Trailer Wiring Kits take the guesswork and frustration out of vehicle to trailer wiring. Each vehicle specific connector is completely pre-wired, and uses original OEM connectors for water tight protection and a guaranteed fit. Each Hoppy Kit provides everything you need for a standard 4-wire flat application. Unplug your vehicle's factory wiring harness and plug in a Hopkin's vehicle wiring kit. That's how easy trailer wiring is with a Plug-in-Simple wiring kit, featuring OEM connectors for a perfect, weather-tight fit! These kits provide a 4-wire flat connector for your trailer. Optional "pre-wired" 4-wire flat to 7-way RV blade round extension adapters are available to custom install the vehicle side wiring to most trailer configurations.
