Dual Relay / Dual Output Quick Fit SMART Harness™ | Our all-in-one wiring loom

Our all-new Plug & Play SMART Harness™ for Quick Fit installation of your driving lights. Incredible High Current 10AWG cable, negative switch compatible, waterproof switch. Our SMART Harness™ has been designed around the consumer to simplify the installation process.

The supplied HB3 and H4 Adapters trigger your driving lights from your high beam without cutting or soldering any wiring. Simply unplug your HB3 or H4 connector at the back of your headlight's bulb, plug in our adapter, and you're done! Driving lights will only trigger from a high beam, and the switch will act solely as an isolator.

Our new SMART Harness™ has a built-in microprocessor that automatically detects whether your system is positive or negative switched and will work right out of the box without any modification whatsoever. Toyota's, Ford Ranger, Mazda BT50 among many other popular 4x4 are notorious for being very difficult and costly to wire driving lights to high beam, our quick fit harness takes all the guesswork out of it.

It contains everything you need to get your lights connected: ON/OFF Switch, 60A Relay, 35A Fuse, ribbed cable protectors, heat shrink wrapped relay.
