I'd say it's part of some aftermarket accessory that a PO put in or had put in - maybe part of an alarm system, or car audio accessory?

I agree, but it definitely controls the A/C. With it disconnected the A/C doesn't work at all. The other "A/C relay" does something with idle control. With it disconnected the idle doesn't bump up to compensate for the extra load on the engine. I almost wonder if this was some kind of aftermarket A/C system installed after the car arrived stateside.

Still no "aha" moment though. I had my wife help me for a few moments and I was able to confirm voltage does increase with engine speed but not nearly as high as indicated on the gauge.

I also figured out why the steering wheel was so sloppy. Some kind of plastic o-ring at the end of the steering column has completely rotted out. Not sure if I'm SOL or if there's some way to replace it.
