Mysterious wiring harnesses next to my amp. 700

During my quest to figure out why neither of the speakers on the driver's side of my car work, I took off the panel underneath the steering wheel and found three wiring harnesses that aren't connected to anything. I can't figure out what they are or where they go. Are they supposed to be like that? Here are some pictures.




Man it's hard to get a good picture under there! The largest of the three has 8 connectors and is white. Next there is the yellow one, with 6 connectors, and a small single connection wire.

Does anyone know what these connectors are for?

Thanks for the help.

i can't say for sure but i THINK mine had those also. i don't have cruise control, so that might be a good guess. *shrug* i've learned to ignore most of the connectors hanging around, as i encounter at least 1 in practically every part of my car ;)

Do you have cruise control? If not maybe it's the cruise control wiring? I'm just guessing though.
