Circuits F71 supplies battery voltage to the Automatic Temperature Control (ATC) module when the ignition switch is in the RUN position. Circuit F6O from fuse 8 in the fuse block connects to the ATC module. Circuit F6O is HOT at all times. Refer to General Information. Circuit Z1 provides ground for the ATC module.

Circuit E2 from the dimming module connects to the ATC module. Circuit L9O from the headlamp switch supplies power for illumination to the ATC module when the headlamp switch is in the PARK or ON positions.

Circuit G25 from the US/Metric switch in the overhead console connects to the ATC module. Circuit G25 also connects to the Vehicle Information Center (VIC).

Circuits D1 and D2 for the CCD Bus connect to the ATC module. Circuits D1 and D2 also splice to the Powertrain Control Module (PCM) data link connector.
