I have a multi color harness that I have no idea where it goes to. It has a black hose attached so I'm guessing it's the smog system/canister hose. I also have a couple harnesses in the firewall that aren't hooked up. One is pink and grey. The second is a single green wire. Any idea?

Cruise control. That end of the harness plugs into the cruise module, the hose connects to the brake pedal vacuum switch.
