since I have an "ocean" of the cat5 (computer network wiring, four or more 24ga conductors per sheath) stuff laying around here, and very little of other, bigger gauge wire, I'm thinking of wiring the towed car rear lights with cat5 from the towed vehicle. I realize 24ga is probably 'undersized' for a 'one wire per function' (brake/turn left, brake/turn right, running, and ground) deal, so I could double it up, and make it two conductors, or more, like 3 conductors, per function. they could 'share the load' :-). it'd all be soldered and insulated, taped, zip-tied correctly, of course.
I don't feel like romping out and buying, like 20 or 25 feet of four conductor 'heavy gauge' stuff for a 'one time use' situation. also have a pretty fair amout of, i think, 14ga three conductor romex...
thanks for thoughts, comments, and alternate ideas :-)
