B+ needs to go to the battery and loads (recommend 10GA wire minimum).
D+ goes to the warning lamp, 18GA is adequte. The other side of the warning lamp must have power supplied to it from the ignition switch as in a stock bug - voltage fed to D+ via the filament of the bulb provides the "field flash" to get the alternator going initially.

There's a ground screw on top but it's not vital since the alternator should be well-grounded via the pedestal & strap (don't paint the pedestal saddle)...and if you were relying upon the little 16GA wire usually connected here for a ground you'd have problems anyway, a wire that small couldn't handle the charging current.

THANKS MARC.
WOW THATS GREAT,YOU REALLY SOUND LIKE YOU KNOW WHAT YOUR TALKING ABOUT!
ITS NICE TO GET A STRAIGHT ANSWER
JUST TO GO OVER IT TO MAKE SURE
B GOES TO POSITIVE SIDE OF BATTERY ??
D GOES TO LIGHT AND THEN TO IGNITION SWITCH,SHOULD THAT BE THE START CONNECTION OR THE RUN?
THANKS AGAIN

Warning light should be wired to run on ignition switch.
