w108 280se 4.5 internally regulated alternator wiring help!
purchased a bosch 90amp internally regulated alternator from a audi 4000/vw quantum and am going to attempt to wire it up tomorrow when it arrives. my question is this. to those of you who have upgraded to a higher output alternator, what did you do with the 3 wires going into the factory plug that plugs into the side of the alternator, and the 1 heavier gauge wire with the boot on it which i assume is for the battery connection. any ideas of how i should wire up the new alternator with these 3 wires as the connection on the new 90amp alternator does not have a 3 prong female connection on it. is it possible to just make a new cable from the alternator to the battery since the new one is internally regualted? can i just bypass and leave the old externally regulated wiring alone, or do i need to tap into that and still use it? thanks.
here is a photo of the 3 wires that go into the plug on the original alternator.
