FOR CARS WITH HIGH ALTITUDE SWITCH
Some Subaru models have a High Altitude Aneroid Senosr Switch which is mounted in the location where the Cruise Control Vacuum Valve and Reservior are installed. (FIG. 1) On these cars the High Altitude Switch should be re-located as follows:
1. Remove the High Altitude Switch from the firewall and move it out of the way. The wire can remain connected.
2. Install the Vacuum Valve and Reservoir according to the Cruise Control Instructions.
3. Re-install the High Altitude Switch on the Vacuum Reservoir bolt nearest the spare tire. (FIG. 2) Be sure the High Altitude Switch is still connected to the cars wiring harness. (Black, 1 pin connector.)
