Hi I have installed both driving lights and light bar, I have ran two plug and play harnesses and switched the polarity as it is in a 75 series. I have then plugged the piggy packs into each other and before my jtx supplied canbus (I’m running jtx led headlights).



I have two issues:
Firstly the light bar and headlights won’t turn on together. I can turn them both on and off independently but not have them both on together.

Secondly if Im on low beams and the light bar and/or spot lights switches are on (either switched them on while in low beam or flicked high beam off while the light bar or spot lights where still on) then the switches turn my high beam on, even though in cab my high beams are off. I presume this would be a road worthy issue because if I have the switches on and turn off my high beam while it turns off my lightbar and spotties it prevents my headlights from switching to low, unless I turn the switches off.

Hi Alex
What exactly isn't working? Are the lights not switching on or are they only on when you have low beams?

Hi Guys, just purchased and installed 24 inch light bar and plug and play wiring kit. All went together fine, just doesn't work. I have checked all the fuses and high beam still works through the piggy back wire. Any ideas? Cheers

I figured it out. H1 headlight piggy back plug was really tight and hadn't gone in all the way. All sorted

Is the car turned on, switch on, then turning on high beams?

I bought some work lights to fit to the tray. The shop attendant said to get “this” harness instead of “that” harness and just wire it in as if they were driving lights instead of work lights. I’m fine with the way the lights work when wired in. Except that the Deutsche plugs don’t reach the tray. Is there an easy way to extend them? Can I buy extensions from you guys?

Hi - So proud of myself (electrical newbie) for installing the Dominator8 - 7 inch spotlights & I guess the smart harness (purchased June 2021) as per your video - its a toyota Hilux 2010 kun26 - my car lights work fine - but the spotlights - when the switch is on - work only on low beam not high beam - it all works fine but on low beam & turn off on high beam - have a reversed something??? - though the plugs only plug in one way so I cant work out exactly what the problem is - thanks - Don

Are you 100% sure you purchased the smart harness and not the standard? If you still have the box or your invoice what is the SKU of the harness you bought?

Had another go yesterday, and it turns out it was just a very stuck plug.. It had the correct plug and it is working fine now. Are the two relays different, as it worked with one but not the other.

Bought kings 7" LED driving lights and plug and play wiring harness, when about to install on wife's Captiva noticed her lights are H7, is there an easy way to connect to high beam seeing plug and play adapters wont work on H7 connections.

Hi there,
We advertise our wiring harnesses to come with H4 & HB3 headlight adapters which are the most universal fit for most vehicles. If your car is a H7, you can purchase a piggy adaptor which will let you connect the wiring.

I have a 2021 gwm cannon ute, it has constant power to run all the headlights and everything and only very light small wires to trigger (about 8) all the different things like adjustment height, indicators and lights. Should I take the trigger wire from the high beam trigger wire or elsewhere to run the smart relay for led lights.

I took delivery of a Kings Big Daddy Deluxe swag a week ago. The mattress has been out of the packaging for 7 days and hasn’t expanded properly. I’m going away in 10 days and I need the mattress! Are there any tricks to get it to expand? If not I need a replacement ASAP.

Undo valve completely

It’s just the standard mattress, not a self inflating type. No valves. The packaging has compressed the foam so much it hasn’t bounced back

Hi, I have recently purchased the Kings Number plate light bar with the Smart wiring harness. I have fitted both to a 2022 Holden Trax as per videos on your website. The Trax has HB3 connectors to the lights, so I am using the HB3 piggyback adaptor. The light bar is on whenever the lights are turned on (both high and low beam) and only turns off with the switch. Is there any advice on how to rectify this?

I purchased a slim line LED light bar, when first wiring it up, the light bar would switch on without headlights, on with low beam and off with high beam. Thought this could be mean it was negatively switched, after following your diagrams, light bar comes on when switched on and lights off, off on low beam and on on high beam. Remains on when headlights completely off, what could I be doing wrong? What can I do to fix this?

We have the Kings 60lt fridge freezer. Perchased a few years ago. We have been very happy with this product. One our Recent camping trip it stopped working on the 12 volt phase, 240 works fine. We checked 12 volt fuse which is ok, my husband had solar panel hooked up a the time, and it stopped working. Any ideas?? who does repairs? any help would be appreciated. Thank you :)
