THE DEVIL IS IN THE DETAIL.
Whilst others claim to be universally compatible with both positive and negative switched vehicles, you'll soon discover that this is not the case. The STEDI SMART Harness is unique in that it has a built-in microprocessor which deals with even the most complex vehicle wiring systems. When installing your LED Driving Lights our aim was to create a stress-free process with piece of mind of knowing it will all come together in the end.
BRIDGING THE GAP.
Whether your driving lights use the popular DT or DTP connectors, our SMART Harness caters for both providing a cross-compatibility platform that will lay any confusion to rest. Dual output allows for running anything from a single to dual slim LED Light bar to a set of high performance LED Spot Lights like our STEDI Type-X.
ADR COMPLIANT.
100% Plug & Play, no splicing or grafting required, our SMART Harness will install straight to your vehicle hassle-free triggering straight from your vehicles high beam. With an all-new waterproof switch for open cabin application, included HB3 + H4 Piggy Back adaptors fitting most vehicles factory headlights with H1, H7 & H9 also available, this is your all in one wiring solution.
THE NITTY GRITTY.
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 & DTP to DT Reducers bridging the compatibility between the two connector types. 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.
