Re: Heater Vacuum Hose Configuration

[Kneale Brownson <knotnook@traverse.com>]

In my '86 parts car, Greg, the white tube coming through the firewall
connects directly to a red tube running to the control box in the passenger
footwell.  The red tube plugs into a connector linked to a black and white
tube inside the box that goes to the (whatever they are) motor that's off
to one side by itself as opposed to being in line with the rest of them.
