Hey there,
  I've gotten a lot of great responses as to wiring up the headlights in
my SA grill.  I think I want to set them up as:

Low: 2 outer lights on
High: all 4 lights on

seems the best for my use and surroundings (rural country roads mostly).

I already had wired 1 relay for each of the original lights (the combined
84 round headlights) so my remaining questions now are:

1. Is it necessary to do 2 more additional relays for the inner (high
beam) lights?  The gauge to the outer lights is pretty hardy and I have
very little room behind my dash as it is (old style porcelain fuse panel
is pretty cramped).

2. If I can do it without additional relays and new wires, what would be
the wiring from the outer light to the inner, ie what wire goes to what
terminal to make them function the way I want (low = outer, high = all).

Thanks again for all the great suggestions.
  Tolga
