Light bar wiring harness with Auto polarity switch controlle

[reg_2]

Hi fellow Tritoners

I bought a wiring harness for an LED light bar and I'm failing to understand what some of these wires do.

It has a "auto polarity switch controller" and has a yellow wire labeled "connect to Negative to activate or High beam"

There is no wiring diagram.
Please help.

Does the yellow wire connect to a relay ? Maybe give us a photo of that ?

[reg_2]

No it doesn't.
How do I post a picture here?

I'm on a mobile

Have a look at this thread - about a quarter way down the page ...

Ahhh - well, that may be an issue - I'll PM my mobile number. Send photos & see where we can go from there ...


Q

[Quinny]

Ok - lets have a look:

Is that clear or do you need separate pics of each component?

[Quinny]

Maybe full size:

The blue Narva looks like a relay ... anyone know what that black box is ?

[reg_2]

Yes. Blue is relay.
Black is labelled auto polarity switch controller

I'll wait for other comments, as I've never dealt with LED driving lights before, but I don't think you need it...

All you need to do is pick up the high beam to switch the relay to turn on your light bar ... You'll need a fuse in there somewhere ... I'll see if I can find a wiring diagram ...

Thank you Quinny

There is a green (striped red) marked negative at the relay end as well

Does that câble got something to do with polarity?

Sorry mate - got a bit distracted with work and a broken lawn mower

How did you get on ?

[reg_2]

I got it wired mate. I had to tap into the high beam wire. Once I figured it was, it was easy. Difficult but was routing the cables

Attempting adding couple two led bars (4 inch) for the back. Reversing. I guess you could just tap into the reverse wires?
I'm also looking at putting couple of them on the sports bar, facing backwards to come on with the reverse lights.

Do they have to on switches, like the forward facing driving lights?

Sorry mate - work again gets in the way ...


Yes, definitely switch them ... You don't really want to light up the surrounding neighbourhood everytime you're reversing your ute ... and as an added bonus, you can turn on your rear facing lights when setting up camp, without the keys in it (and in reverse gear) ...
