I've got a 90 f-150 5.8l 4x4. I was given new 100amp alt for a 1990 E-350 5.8l van. Now the connectors are different between the two.

Does anyone know how to wire it up correctly?

I think I might have it down.

The plug connector wire "A" - goes to battery terminal ring
wire "S" goes to stator terminal but I cant seem to figure out where the "I" wire goes to. Also the old stock alternator had a wire next to the positive post, that wire goes to the stator also correct?


Thanks guys!
