While relpacing the cruise amp on the 87 300TDT, I had the pad under the steering wheel removed and I noticed a vacuum line loose right next to the ignition (to the right). Checked the two lines going into the switch itself, but they were both there. This loose line has a rubber fitting on it, so I figure that it goes somewhere really close by.
A/C, door locks, glow system, shifting, all works, but I figure that this line isn't just hanging out for no reason.
The line is brown or black, and the connector is black. Any takers?
