Universal wiring harness with a built-in microprocessor that automatically detects positive or negative switched vehicle systems. 100% plug-and-play — no splicing or grafting. Includes dual DTP connectors (with DTP-to-DT reducer adaptors), HB3 and H4 piggyback adapters, a waterproof switch, 60A relay, and 35A fuse.

Triggers driving lights via the vehicle's high beam circuit without modifying factory headlight wiring, and lets you run two sets of driving lights from a single harness.

Key Features

Connector Type Dual DTP (with DTP-to-DT reducer adaptors), plus HB3 & H4 piggyback adaptors
Wire gauge 10AWG
Relay rating 12vDC 60A (heat-shrink wrapped)
Fuse 35A
Max load 35A @ 12vDC
Total wiring 4.8 metres (6.4m fully stretched)
Plug-and-play Yes — 100% plug & play, no splicing or grafting required

Highlights

  • Runs two sets of driving lights from a single harness via dual DTP outputs
  • Microprocessor auto-detects positive or negative switched systems
  • No splicing, grafting or soldering required
  • Triggers off the factory high beam circuit without altering headlight wiring
  • Includes HB3 & H4 piggyback adaptors for common headlight bulb types
  • Heat-shrink wrapped 60A relay and 35A fuse for weatherproof reliability

Compatibility

Works with most vehicles using H4 or HB3 headlight bulbs and a standard high-beam trigger circuit. For vehicles with factory LED headlights and non-standard connectors (e.g. Isuzu, Jeep, BYD, LDV, Holden, Mazda, Nissan Patrol Y62), pair this harness with the matching STEDI vehicle-specific piggyback adapter.

How to use

  • Mount the waterproof switch and run the relay/fuse assembly in the engine bay
  • Connect the HB3 or H4 piggyback adaptor behind your factory headlight bulb (or a STEDI vehicle-specific adapter if fitted)
  • Plug your driving lights into the dual DTP connectors (use the included DTP-to-DT reducers if needed)
  • No cutting, splicing or soldering required — the microprocessor auto-detects your vehicle's switching type

What's included

  • SMART Harness with dual DTP connector
  • DTP to DT reducer adaptors
  • HB3 & H4 piggyback adaptors
  • Waterproof ON/OFF switch
  • 60A relay (heat shrink wrapped)
  • 35A fuse kit
  • Ribbed cable protectors
  • Instruction leaflet

Frequently asked questions

Do I need to cut or splice any wires to install this harness?

No. It's 100% plug and play — the HB3/H4 piggyback adaptor plugs in behind your factory headlight bulb with no splicing or grafting required.

How many driving lights can I run off this harness?

The harness has two DTP outputs, so it's designed to run two sets of driving lights, up to a combined max load of 35A @ 12vDC.

Will this work on my vehicle if it has positive or negative switching?

Yes. A built-in microprocessor automatically detects whether your vehicle's high beam circuit is positive or negative switched, so no manual configuration is needed.
