Light bar Install - need ignition source

Searched but didn't find exactly what I was looking for. This is not in my wheelhouse so want to make sure I get it right. I have a Headlight Revolution stealth light bar that came with a GTR halo switch. I have everything hooked and the switch turns on and off the LB without issue. I'm now need power to light up the halo switch at night when my other factory switches light up. To do this I want to add a circuit to my fuse box and I'm looking for recommendation on which fuse to use. I was thinking either the 7.5 ACC or Panel but the inline fuse they gave was 10A. Since I'm adding a circuit I'm not using the inline fuse but wasn't sure if that meant I should add my circuit to a 10A fuse. Thanks for any advise.

Thanks for the link. That worked but not exactly what I was looking for....I might just leave it as is. Right now, the halo lights up whenever the key is turned to ACC or ON as opposed to the other factory switch lights illuminate when the headlights come on. Still, looks cool. Thanks again for the quick reply.

 

Good idea. Thanks

 

I purchased this boost gauge and it needs a 12v source. Would it be okay to just tap into my positive and negative wires from my halo switch instead of adding a circuit on the fuse box? The halo switch wires are right there and readily available. Appreciate any advice.

Just did it. Worked out well. Just don’t know where to plug into the SC now. Thanks for the boost of confidence.

 

Take a look though my compressor install, i did find one in the main fuse block.

Thanks Ron...

 

OKAY...I don't what you do with that but it is very cool.

 

I like the P3 gauge. I want to do one for my Tundra to read the MPH. Have you tried your gauge for speed? I was wondering if it changes rapidly (flickers between numbers) or if it is pretty stable to use as an actual speedo. I'm assuming you got the OBDII version, if not then you won't have the speedo option. Either way, clean install!
