DETAILS

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.

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

  • Featuring a total of 4.8 meters of wiring (fully stretched out)
  • 2.4m of cabling from Relay to Switch
  • 2.0m of cabling from the Driving Light connector to Relay
  • 2.0m from H4 or HB3 Adapter to Relay
  • Total cable length 6.4m
  • 12vDC 35A Rated Fuse Kit
  • 12vDC 60A Switching Relay
  • Push Button ON/OFF Switch
  • UV Rated Insulation
  • Instruction included.

HB3 & H4 are the most common wiring connectors found in most popular makes and models. If your car does not use H4 or HB3, this wiring harness can still be used to connect to a high beam. We also sell separately H1, H9 & H7, as well as vehicle-specific adaptors for the Amarok, 200 series Landcruiser, MQ & MR Triton, Isuzu M-UX / D-Max, Ranger / Raptor PX2 & PX3 7 Holden Colorado.

Great fit for a 2005 Honda Element
These fit my 2005 Honda Element perfectly. Solved a small leak issue. I’ve had these installed for about one season so far (winter into summer) and they are still holding up. The install is simple if you’re confident working on your power steering system. Overall happy. No complaints

Buy OEM Honda for $2 - Suction side o-ring does not fit right
No good. Suction side o-ring doesn't fit right and immediately sucked air. Spend the $2 at a Honda dealer and get the original orange 91345-RDA-A01 o-ring. Fits much better and instantly quiet power steering pump.
