Here's how I installed my cheapo lights, really just to test out some lights that I don't care much about losing since I don't have to have them for the wheeling that I do. I was surprised at how bright they are, now to get some good KCs or something.
For this install, I ordered in a painless wiring kit and used some LED switches from the local auto parts store. I plan on adding an extra switch just for turning the LEDs on/off on the switches as they may get too bright for wheeling in the dark.
First of course, I had to install the lights, if I recall, I tested them directly on the battery to make sure they worked. I'm not a professional folks, so don't try this at home. I installed through an existing hole on my RR bumper and had to drill a hole for the other side. Like a good obsessive-compulsive Jeeper, I touched up the bare steel with some black paint.
Next, I installed the 7-fuse block. This wasn't easy, I need to learn to remove the seats to make this type of work easier. I'm not a 17 year old kid anymore and being upside down for more than 30 seconds makes me feel like I'm about to lose consciousness. Sorry for not rotating the picture, maybe turning your head will give you an idea if you're up to the task of trying to install one of these. The painless fuse block came with self tapping screws, after anchoring them, everything seemed to work and since I installed all this last November in Delaware, I don't think I hit anything that I'll miss.
Next I installed the circuit breaker under the hood near the battery.
I also mounted one switch above the rear view mirror. Added a second switch to test the LED on/off idea, some day I'll need to finish all the wiring and add some backup lights, maybe some lights by the pillars and some undercarriage lighting for nighttime crawling (not for the night-time lowrider look).
While I was pulling wiring around, I threw in a piece of cat-5 in hopes of getting some relays and testing out something like that. Haven't had time to go wheelin as much as I'd like, sure not going to tinker.
