I’ll start by saying I am a total novice with electrical work. I’m handy, but I know hardly anything about electrical. This was very easy to install for me. I put this on my fishing kayak, to control power to my bow lights, deck lights, and graph. I watched a couple YouTube videos to make sure I was comfortable going into this install and it was really quite simple to get everything hooked up and running off my 12v battery.Very happy with this rocker panel. Gives me the switches I needed and USB ports to charge my phone/GoPro/whatever, and it was easy to setup. Would recommend.
