Legends, thanks guys, I'll give it a stab tomorrow. I'll also be sure to note the positive cable before taking the connection off and wiring it up.

The matching connector for the GPS Supply is same as that used on indicators, a well known auction site invariably has sets for sale, and as I recall are waterproof.
