If it's the stock Bosch alternator, I do believe the regulator is on the outside of the alt housing. Therefore you should be able to easily unbolt the old one and hook up the new one. I, unfortunately, have a Delco on mine thanks to a PO who believed in monkeying with a good thing, and the regulator is on the inside. So I've actually got to remove the alternator for any work. I think the Bosch regulator looks like a black box about 3 inches long on the rear of the housing.
