HOT
In twelve volts (using black and red wiring) the red should be positive and the black negative. I don't know what receptacle you have but the center should be positive and the outer ring negative. K

WATER TYPE DECK CONNECTORS
THANKS FOR THE HELP GUYS. LET ME CLARIFY THE CONECTOR TYPE, THESE ARE WATERTIGHT DECK MOUNTS. THEY HAVE A LARGE AND A SMALL ROUND MALE AND FEMALE CONNECTORS. DOES THE BLACK GO TO THE LARGER SIDE OR THE WHITE?

Don't think it matters?
If you are making a disconnect for the mast light, just pick one as positive and be consistent. If you are making a recepticle to plug other items, use a 12 voly type receptacle.

I'm not quite sure what you are asking but maybe this might help,general speaking the hot side(postive)is always larger and the ground is smaller.

FYI
On a 110V plug, the larger (wider) plug in the neutral and the narrower is the hot! On the 12 volt deck connecter, both condutors can be positive to supply two curcuits if you can find a common negative. ie. mast base or if it is a metal connector and not rubber, you can rig it that way too. 12 volt with low amp ratings can be very forgiving if FUSED properly.

Not a good idea...
...in fact a very BAD idea, to use the two pins on a connector both in parallel as +12v live pins to increase current capacity, and use a connection to the mast as the return, as suggested by Mark. On a boat each dc circuit MUST have a complete separate return all the way back to the common ground point. You are asking for all sorts of galvanic/electrolysis problems if you rely on connections through the standing rigging etc for your return path. You do not want stray dc currents flowing through any of the rigging/bonding. I believe the ABYC specifies you must NEVER, NEVER do it. Derek

ABYC Requirements for
The very first entry in the ABYC specs under Electrical, General Requirements is: E-9.5.1 Two-Wire System - All direct current electrical distribution systems shall be of the two-wire type. Using a common negative conductor for several positive conductors is convenient, but against ABYC standards and counterproductive in the long term. Using structural items as a negative conductor is BAD!
