My "new" '74 Duster- or why I need a project like a hole in the head

Are the double crimpers for crimping multiple wires into one terminal? I assumed it was for crimping both the wire and the insulation at the same time.

I've been looking for a crimper that will do multiple wires in one terminal and come up blank so far. Guess I need terminals that work for that, too. Haven't looked for those yet.

Yes, the blue handled crimpers are for the crimping the doubles (or larger gauge wires). It's a different terminal too, has larger wings to accommodate the double wires.

AA refers to the one as a double and the other as a single, although really its just about the gauge of the wire(s) and size of the terminals matching up with the size of the crimper. Each crimper has two positions, one for the bare wire crimp and one for the insulation crimp.
