Wiring KC lights help

I have a 2004 TJ and I recently got a pair of KC HiLites Daylighters. I mounted them with windshield mounts. Now the problem is wiring them. I have tried multiple times. The "instructions" don't properly show how to do it. I'm 18 and new to all this. My dad has been trying to help but he doesn't have much free time with work. I was going to go to a shop to just get it done but I don't have much money right now. Can somebody help explain how to wire them? It's really annoying when someone ask to see how bright they are and I have to tell them they aren't set up. I really want to just get this done. Any help would be great.

I had a set of 150w daylighters on my old silverado. Absolutely loved them, had them for 8 years and they never once rusted, and the wire was loomed throughout and never had a problem. Had a couple bulbs go out over the 8 years but that's expected. I wired a set of hellas a couple weeks ago to my new tj and I used this writeup

The Trekker's Journal: Hella 500FF Driving Light Installation

I imagine its the same for the daylighters...

What you need is an offroad driving light wiring harness kit which includes a relay so the lights operate at full brightness and the switch isn't overloaded which makes it burn up.

Any 4x4 shop will have a pre-wired offroad driving light wiring harness and any brand will work with your KCs. You can get a Hella, KC, PIAA, etc. brand kit and they'll all work with your KC lights.

The KC lights connect to the pre-wired wiring harness. You connect the heavy red wire from the wiring harness to the + post on the battery and the heavy black wire to a suitable ground connection or to the battery's negative post. Mount the switch and you're done.

The first drawing is basically how it works... click on this to make the animation work. The second drawing just shows a different way of looking at it. The key is the 'relay' which has to be there to make it all work properly... the pre-wired offroad driving light wiring kits all include that relay already wired in and ready to go. Installing it using the pre-wired kit turns a difficult job into an easy one.

Well that makes it easier. The main thing I'm having a problem with is the switch. I think I found a spot to go through the firewall. I don't know where to put the switch. I know there are a few spots that are made to hold switchs but I cannot figure out how to punch out one of those empty pieces.

^^^ Take rocker switch panel out and then just use a flat head and pop them out.
