Stedi Plug and Play Wiring Harness – High Beam Driving Light – Single Connector
The STEDI Plug & Play Wiring Harness offers a quick and easy solution for installing your driving lights. This harness allows you to connect your driving lights directly to your high beam without the need for cutting or soldering any wiring, thanks to the supplied H3 (HB3) and H4 adapters. Simply unplug your HB3 or H4 connector from the back of your headlight bulb, plug in the STEDI adapter, and you’re all set! The driving lights will only trigger from the high beam, and the switch functions as an isolator.
V2.0 Technology The new V2.0 version features built-in electronics that automatically detect whether your vehicle uses a positive or negative switching system, making the installation process even easier. The harness works right out of the box without any modifications, simplifying what is usually a tricky task for many vehicles, such as the Toyota, Ford Ranger, and Mazda BT50, which are known for being difficult to wire for high beams.
