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.

Super cute
Color: Bunny (Mauve), Size: Small
Super cute and fuzzy. Definitely perfect size for a puppy and not too loud. The fur is very soft and the nose is sown on not a hard piece that can be chewed on. Very good quality too.

Normally amazing
Color: Spiky Ball (Blue, Orange), Size: Medium
We have purchased these slightly spiky dog balls several times for our very strong jaw heavy chewer dogs and they’ve been amazing. They don’t break down they don’t get torn apart the squeakers don’t even pop out of them. So we ordered another package because we’ve lost a few outside to the lawnmower… oops and the package that got delivered today had only one ball that squeaks and the other does not. THIS IS A PROBLEM ! Unfortunately my female dog got to the new squeaking ball first and my male got to the non-squeaking ball and he was NOT happy. Basically once they claim a ball it’s theirs and the other dogs don’t go near the ball they claimed. So he’s following my female around and every time she squeaks the ball and I’m just waiting for him to attempt to take it from her causing damage to her. Normally… These are amazingly fun, tough, durable but also squeaking balls (that’s rare in a tough ball) that my dogs absolutely love. This time just got a bad batch I guess. When they squeak the dogs LOVE them. After several months of play the squeaker might break inside of the ball but the ball never comes apart or gets damaged. And we as the owners love that they don’t break down are not able to be ripped or torn even by our very strong jawed and big jaw muscle dogs. They are also great for in the house play because they’re small enough that they fit completely inside our dog‘s mouth but obviously not small enough to get swallowed so when we throw them in the house for fetch the dogs can jump up and catch them fully in their mouth so they don’t cause any damage to the walls when they hit the walls. They’re not super heavy but they’re incredibly durable. Definitely worth the price especially if you have heavy chewers or big jaw muscle dogs.

Best fun indestructible toy
Color: Crinkle Duck (Yellow), Size: Large
Truly indestructible no matter how much our oittie tries. She has owned it for three months works at destroying every day with no success. She carries it everywhere. Best purchase for chewer, more fun than the popular rubber heavy duty toy. Do not hesitate your pup will thank you for this fun distraction.

My dog loves this toy!
Color: Bunny (Gray), Size: Large, Color: Bunny (Gray), Size: Large
High quality, big toy, perfect for a medium to large size dog. After a few months of serious chewing I had to buy another one, but well worth the money! Rocky loves it.

Great toy but if your dog is an aggressive chewer, please think twice.
Color: Crinkle Chicken (Brown), Size: Large
I received this on May 23rd and on June 8th, after playing with this thing every day, our recently acquired 36 lb dog finally ripped it open and got out all the plastic and the squeaky part. Lily Belle will miss you, chicken. Lily loooooved this toy! She'd toss it in the air, chew on it, pull it with her teeth etc. but as much as she loved it, we won't replace it. It's just not durable enough for her. If your dog is an aggressive chewer, you might want to try a different toy. I hate that this lasted just a smidge over two weeks because Lily seemed to truly enjoy this toy. RIP, squeaky chicken!
