OK, a good friend and fellow ih8mud member ordered a set of Hella Rally 4000 Pencil Beams, and one of the Hella connectors wasn't included (the one that clips on the back of the light). In order to solder a new connection, I noticed that there are three wires off of the rear.
One is ground, one is +12v. What is the third? ???
