Electrical is the bane of my existence, but i've got a pile of lights a fridge thats getting wired this weekend (fingers crossed probably not though) and compressor on the wish list.
I shelled out the bucks for a Switch Pro, saved my life from having to do anything crazy or radical wiring wise - relays, switches, whatever. Thats my 2 cents, cater to your strengths and pay for the weaknesses. Really didn't matter how many you tube videos I watched either, i hate electrical stuff.
However, the Blue Sea fuse box is the bees knees.
