I am 99% certain the high pitch sound you are hearing is the fuel pump. That is normal. My '87 930 makes the same noise. The joys of CIS!

Its the whine of the CDI module. Is it coming from your speakers?

Yes, I should have just said that the sound is normal instead of saying it is the pump. But thanks for correcting me as to the CDI. I just know that the sound is normal and nothing to worry about.

what is the CDI? i'm almost 100% sure it was coming from my back speakers when they were hooked up as i lifted the speaker out and held it to my ear...but once disconnected, the sound could be traced to the engine bay. kinda strange.

It's Capacitor Discharge Ignition (CDI)
EDIT: I think there are some good books out there. Do a search here and I bet you'll find TONS of info. I would like to learn more about CIS also.
