I just purchased an OEM fog light switch (p/n 251 941 535) from Bus Depot.
I plan to use this to control a set of Hella 500's (which I will hopefully
be getting for Xmas).  I have looked around the archives a bit and would
like to confirm what I have sorted out and ask one additional question.  All
of these connections assume wiring direct from the battery using 10GA wire
to a fuse block and the relay that comes with the Hella 500's.  I chose to
wire them this way so I can switch them on totally independent of the
headlight circuit.

Connector tab marked (+) - 12V in from battery.

Connector tab marked (83a) - Output to front (primary) fog lights.

Connector tab marked (83b) - Output to rear (secondary) fog lights (also
turns on indicator light)

I am planning to connect my lights to (83b) so I will have the indicator
light as a reminder (it's there, might as well use it).  The post that holds
the indicator bulb has 2 connectors on it.  Am I safe to assume that I need
to wire the tab further out on the post to a good metal ground?

Should I install the Hella relay closer to the switch, or closer to the
lights (or does it even matter)?  Man, I hope Santa comes thru with the
lights for me...

                                                Thanks in advance,
