Wiring and Switches for rack light bar

Hi all, thanks for all the content so far on TW. I've been digging around and I haven't identified a clear answer so I thought I'd post a question here:

On a scale from 1 to 10, what is the effort to install, and wire a switch for a light bar that is hypothetically mounted to a prinsu cab rack? Is wiring this this something I can do myself? I'm fairly handy, but no electrician. Should I be going to a shop for an install? What should I expect that set me back in $$$?

And as I'm looking at ways to do this, I'm guessing I can hook the light bar into my fog lights (not preferred - I want to control them separately). How else should I be thinking of doing this install? Do I need to worry about fuses? Should I be looking at expensive switch panels and the like? I don't want to go overboard. Thanks in advance for your perspectives.

oh, and today, to the lower left of my steering wheel, I have a single blank open. Everything else is 'full'

 

I think that there a ton of variables in your question…

so, are you willing to drill holes in your cab to have the wiring come out? Of the taco in your avatar is the taco in question, it seems that you have the advantage of routing the wires between the cab and your canopy, which takes time, materials, and skill to do correctly while looking good.

How many lights, and where on the rack? What’s the amp draw per light?

do you have any auxiliary switches already and an aux power fuse block already? Is so, where are they all mounted?

do you only want one switch to turn each light/light set on?

do you want high quality GXL (or similar) wire with crimped and soldered, dual layer sealed heat shrunk connections, and weatherproof connectors ? (Hopefully this is a “Yes!!”, but this adds time and money…)

I can keep going on with questions, all of which have near endless configurations and answers, all adding to labor time and equipment costs.

 

Oh, simple answer…

yes, you NEED a fuse.

For some of what you listed, I would run a relay, controlled by the one switch that you have space for, wired through a sealed hole in the roof near the A pillar under the rubber gutter seal.

but, the problem with that simple way is chances are you will eventually want side lights on your rack, so now you would need more wires (and switches) and it’s very annoying to go back at a later time and add more wires, especially through the roof…

I always find myself running extra wires for later projects. Easier to have them and not need them than need them and not have them. Like fire extinguishers, firearms, and frying pans.

 

I did a similar setup for the lights on my "roll bar"/bed bar. I chose this harness because it has 2 pairs of leads for the lights...since these are LED, i was able to double up the connections at the lights 2 lights to each lead.

I did not want to drill into my cab...so I bought some extra red & black 12g wire at Walmart...(it was very cheap) and extented the leads to the lights. So I hooked up the harness as if I was going to mount a bumper light and then ran my extended red/black leads to the lights along the frame, near the brake lines and up the gap between the cab and the bed..and just zip tied as necessary. Came up into the engine compartment as if they were bumper mounted lights. Put it all in some old school wire loom like we did in the 80s.

Then I used a switch from here
