12V plug and adapter - where to buy?

I have looked and can't find two things I am thinking about getting.

1. My Tsunami pump 12V adapter broke after being stepped on and dropped many times. I am sure that a replacement would be easy. The plastic housing says 'safco' on it, but I can't find it anywhere. I'm sure I am just not looking in the right spot.

2. Tige has yet to put a 12V outlet in the rear of the boat. I would use this one to pump up tubes and such. My air pump does not have a long enough cord to reach from the 12V outlets in the glovebox or dash to reach to the transom. It has been a pain to bring a 5 man water weenie or 180 cm tube into the seating area to pump it up. I am considering installing one in the rear of the boat somewhere. Where would I get one?

wal mart? thats where i got my cig lighter plugs and recepticle.

Any auto parts store or even Radio Shack.
