There is no + or -, one is the other side of the other, in other
words the heating element is non directional, just hook them both
up, one to 12v and the other to ground. (Along the normal path,
of which I know not of spec to 16Vs).

You need to be sure the blue wire is really the same Alt exciter
wire that you think it is, if so then YES it goes to the small
blade connector on the Alt (Blue = D+). The (2) red wires go to
the 12v (B+)output of the Alt, you may have an Alt that has
another small blade connector but don't think you need anything
there.
