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.

  • Featuring a total of 4.8 meters of wiring (full stretched out)
  • 2.4m of cabling from Relay to Switch
  • 2.0m of cabling from Driving Light connector to Relay
  • 2.0m from H4 or HB3 Adapter to Relay
  • Total cable length 6.4m
  • 2 x 12vDC 35A Rated Fuse Kit
  • 2 x 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.

Product does not function as befits a brand name like Sony
Review updated after TWO returns to the repair center and MANY calls to both Support and the CS Escalation department: I'M STILL NOT PLEASED WITH THIS PRODUCT. During startup, this receiver bounces back and forth from input source to input source as if I triggered a roulette wheel. Where will it finally stop? In my case, I most often use Video input. Sometimes during startup, it will momentarily display the Video input as expected, but will then start jumping/fishing around to other inputs types, including those I've never used. Eventually, it may return to the Video input, but it will not display the actual video or audio content. Instead, it just displays a black banner that reads VIDEO. I then have to turn the receiver off and on again hoping that maybe it will work this time. Neither Sony's escalation Team, nor the repair facility will answer the simple question, "What SHOULD it do when I first turn it on?" In addition, on at least two occasions, during startup, I saw PLEASEWAIT written across the display for 75 seconds before the device actually started up OR rebooted. (Note: THIS issue appears to be resolved by the repair center replacing a circuit board.) Another related annoyance is that when video content changes (e.g., from a show to a commercial, back to a commercial on YouTube), each break in the chain displays 5+ seconds of black screen even though you can hear the audio. This doesn't sound like much, but when it does this every time, it gets annoying AND is infinitely longer than my previous 10 y/o receiver.) About 2-3 times an hour, while viewing consistent content from the same input, the screen will suddenly go black, then the audio drops out, and then it will flash a HDCP 2.3 warning blue screen. Unacceptable! In short, and IMHO, the audio quality is very good, but basic functionality is SEVERELY clunky. Again, IMHO, this product should have NEVER gone to market. The combination of poor functionality AND a dismal customer experience forever diminishes Sony's former world-class brand status. P.S.: Sony's Escalation department told me that they simply DO NOT provide refunds if you've had the product more than 30 days. So make sure that you test ALL functionality as soon as it arrives. Caveat emptor.

Great price
Color: 14 AWG, Size: 20 Feet
I almost gave it 4 stars cuz I'm not 100% on the gauge being accurate. I have some 16 gauge kicker wire from a long time ago left and it's barely thicker. Granted I don't have a measuring tool so the kicker wire could be over sized but no matter what this wire is close enough to right if not exactly right. But even if it was slightly under for I think $13 it's still a very very good price so if I could verify it was 14 gauge exactly I would give 6 stars

Easy to use and great value
Color: 14 AWG, Size: 500 Feet
Im currently installing over 50 speaker pairs in 4 zones in this remodel. This is a great value for money. The wire pulls easy outside of the box. It is very flexible. and so far we have not seen any internal breaks in the cable. Great value
