Can I wire the negative return from the light to a negative/ground of one of the other circuits? Or does each circuit need its own negative/ground? I ask because I wasn’t able to find the running lights circuit (I think the wires are glassed in between the headliner and the deck, actually) and there is an unused wire running from the port hanging locker to the starboard settee (where the rest of the mast wires are staged). Running duplex along that route would be exceedingly difficult (it’s crazy tight with other wires already) and I’d like to avoid it if I can. -- Andrew Means S.V.
