Wiring your light bar

[Warrenpfo]

To try and keep all things lightbar in one thread I thought it a good idea to post here. I have received my light bar in the mail from the USA and now want to wire it up.

It has come with a wiring harness made up of the following,

Fused Pos+ and a Neg- from the battery to a relay with an on/off switch and then the Pos+ and Neg-that runs to the light bar.

My first question is why are there three wires running to the on/off switch, it looks like a pos+ and a neg- and then one other which looks like another pos+.

Secondly I want to wire the light bar in the following way. I have a carling on/off/on switch in the cab and want to have the light bar either on all the time, off or switched on when the bright lights come on.

What is the best way to wire the bright light switch part?

This is just a guess but my old driving lights have a 3 position switch - off, on and on only when high beams are turned on. I'm guessing the two positives you mention are for these two "on" modes.

The two positives if they are both positive go to the current on off switch on the wiring harness. I am going to have to cut the switch off and re wire the new on/off/on switch to do the job i want.

If i said it was from Okledlight bar that might help explain what i am talking about.

We accept no liability whatsoever for loss or damage caused by wiring your light bar .The brake light bar to ensure correct clearance at the radius ends and along the edge where the filler inserts will be located .

2 weeks old thread, but you probably have a dual throw switch SPDT. One of the outer poles is connected to the center when switched one way, the other is connected to center when switched the other way. You only need center and one of the two outer ones, which is what a SPST switch is.

You don't need to run the grounds at all. One pole of the control circuit of the relay is ground, run it to the mounting screw. The ground from the light bar can also be run to a mounting screw. It will simplify trying to figure out what goes where. The other side of the control circuit of the relay goes to the switch outer pole. The center pole of the switch goes to 12v. The output circuit of the relay goes to the light bar and the input circuit of the relay goes to 12v.

Switch the switch on, the relay clicks and 12v goes to the light bar.
