911 Alt wiring help !

[Sandeep]

Hi all,

I need some help wiring up this 911 alt that I have. The model # is :



The rear of the alt looks like this :



From what I can tell:

1. The two terminals on the top are labeled B+
2. The terminal in the middle, left is labeled D+
3. The upper spade plug is labeled DF
4. The lower spade plug is labeled (I think) D-

Questions:

I'm hooking this up to a 74 beetle with external regulator so I'm stumped as to where I connect the B+ wires on the alt. Does this alt have a built in regulator ?

If so, do I bypass the stock external regulator, and if so, where do I hook up the charging light for the dash ?

Or is this a generator instead of an alternator ?

All I have left to do is install this alt and the BAS exhaust and I can get my car on the road !! so I am really excited !!

Thanks for any help anyone can provide.
