I have a dash cam and with my previous car I just let the wire hang from the camera to the cigarette lighter. However with my GP the lighter socket is much further back in between the seat and not on the dash so I decided to do something about it. I was going to tuck the wire up under the roof and down the pillar to the passenger side fuse.
Got an add-a-circuit and a socket. That added 2 fuses, and the dash cam power plug also has its own fuse which makes it 3 total fuses for one circuit.
I could have snipped the plug off and eliminated fuses but the plug has internal 12v to 5v regulator and I don't want it exposed sitting around under the dash. Plus I'd have to re-hack if I need to replace the plug in the future. Leaving the socket would save me a few minutes later. I did snip out the one fuse inline to the socket. Plus label printer to print out "MAX 2A" on the socket for future reference since 2A seems to be the smallest standard ATM style (socket can do 10A but I doubt I'd need 3 10A sockets). The dash cam needs maybe at most 500mA.
FWIW I plugged the add-a-circuit into spot labeled power roof, since I don't have power roof.
