Thread: Kings light bar

I cant help you more. I don’t think you understand electronics enough maybe Google some images of relay spotlight setups and you’ll work out what you need to do. I used the same kit and it was simple (for me) but I’ve been wiring cars all my life.

Yes I’m missing something basic due to fact there’s no piggy back option for the Disco headlight plug.

In a normal DIY situation you only have the trigger wire from headlight to the relay via the cabin switch correct?

Is this the wiring harness you have PerthDisco?:



Looks to me like the red wire on the 2m headlight connection lead is used as the trigger and the one you modify to tap into the high beam. Black would then go to ground to complete the trigger circuit.

Exactly. It’s that simple. Good work finding that image. I scoured but couldn’t find what you have

Yes it is and I wired as you suggested red to the blue/grey LH light wire and black to earth but didn’t work. More experimenting today.

In fact I created some sort of headlamp shutter blinking and no spotlight activation so shut it down pretty fast.

It’s a very nice piece of kit and I installed on our 80 series with the H4 adapter was an absolute cinch.

I’ll try and simulate the trigger with a seperate 12V supply to check the harness works.

Which headlight configuration do you have?
Main + Infill?

The Xenon version but it seems universally that the blue/slate is the high beam feed.

I’ll test that also today.

That would be the next thing I would try as well.
