single pole, double throw, ie, there is a normally open and normally
closed terminal.  Two coil connections, three signal connections, one of
which is always connected to one of the other two.  I do not have any
part numbers, I have scrounged used Audi relays (ok, from my table, 431
951 253 D is one).  Should be easy to find, though.

example of use: the bottom right rely in this diagram:

and in this one, I achieved this effect without any fancy relays, all
simply SPST NO units:

Uh... duh.  Yes, that's all you need, silly me, is a single pole
normally off relay that is switched by the difference between the turn
signal and parking light wires... sorry about that!
