Honestly, I have no clue. The plan for right now it to mount a XM Radio into my over head console. The supplied power plug is a 5-Volt power plug that plugs in to the accessory ports. I don't want to have the plug hanging down to the dash. I have already run the antenna wire to the console, and was hoping to just chop the plug off if there was a 5-volt line somewhere to tie into. Right now i am thinking of splicing in an extension in the middle of the wire and hide a 12-volt socket under the dash so all the wires will be hidden. Hope my ranting isn't confusing....
