Looking at the rear of the alternator, the pins look like this... |_|

The left vertical pin is marked "L", which is for the idiot light, I'm not
sure if it would go throuh the light to +12v, or to ground.  You would have to
check on that.

The bottom one has a zero with a diagonal line through it, which I take to
mean that it isn't used,

The right vertical pin is marked "Ign".  I believe this is to be a switched
12v (I didn't tell him it was for an a/c).

        There is a large stud that goes to the battery.

This is exactly what I needed to know. Thank you.
