Specifications
The CURT Electrical Adapter provides a quick, simple solution for mismatched trailer and tow vehicle wiring. This adapter allows your vehicle's electrical socket to connect with a different trailer plug type—for example, adapting a 4-way flat vehicle socket to fit into a 1-1/4 license plate light hole for a convenient, ready-to-use attachment point. It features quality plastic construction, requires no splicing, and comes with a protective dust cover. Solve your connection issues instantly and tow with confidence, backed by CURT's one-year limited warranty."
