Hi I don't know how much you will use the cb but if you pull the cup holder black thing out, you will find a compartment under it. I keep my 350watt inverter in there. I don't use it much but when I do I just pop the holder out and plug it in. There are some clips that hold it down tight. I cut them off with a knife to make removable easier. There are all kinds of wires there to tap into for power. I was looking for a key controlled tap point the had heavy enough wire to run a transfere pump. Spent over a hour in cab and never did find one. From experience
I know I'll walk away and leave it on if I don't key controll it. If anyone finds such a point I could use the info. Dan
