My engine has four wires coming to old Mando alternator. A black to the ground, a purple wire to the "EXC" post, a red wire with a purple stripe to the "S" post, and an orange wire to what I think is the pos or charging post. I'll have to call DB on Monday but in the meantime does anyone know how you incorporate these old wires to a more modern alternator. The new alternator is the DB ADR0299. The posts aren't labeled at all and it came with no diagram or any instructions.
