Hi Sean, I agree it is nice to have a dedicated spot for collecting everything 780 in one place. These are special cars and are becoming rare.
As for your two problems, what engine does your car have? The idle problem I would first check the entire intake path for leaks. Check all hoses, gaskets etc. for tears, bad connections and other vacuum leaks. The electrical issue is weird, sounds like a problem with the connection to mass. It it almost looks like the high beams are connecting everything to mass. Any loose or broken wires near the mass points?
