Regulator wiring help

[Jeff Tanko]

Our new original style wiring harness does not jive with the later square style Bosch voltage regulator we have. I know all the wires are there, but I don't know where they are supposed to go. A most are self explanitory, but some are not.
On the harness I have wires for:
D-
D+
DF
D51

On the regulator I have:
B+
DF
D+
61
D-
and a long wire comming off the bottom of the regulator

The like labels I can match up, but I need to know where the unlike ones go(specifically B+, 61, and the long wire comming off the regulator, and D51 in the harness).

Thanks for the help.
