I have installed a Power Socket under the dash and was wondering how someone else has wired their unit up. I bought the socket from DelCity

but it has no amp rating so I'm a little confused on wire gauge and fuse size. My original thought was to run a 14 gauge wire from battery to it with a 10amp fuse in between but I would have to run another wire through the firewall and hoping to "tap" into something handy. Like say for instance the RF radio memory wire.

Any guidance is much appreciated.
