Pinout to up RPM when AC is on

[ssidener]

Have a 2002 LS 5.3 DBC with a A/C pump converted to air compressor (tires/ tools/etc.)

I have the A/C pump wired directly to a dash switch to turn on/off

I would like the somehow tell the PCM to increase the RPM's when i turn this switch on.

Any recommendations? Wire pinout directions would greatly be appreciated.

Need to know what your ECU connector colors are to determine your ecu pin outs. Are you trying to just compensate for the additional load of the compressor being on or idle the motor up like you would for a PTO? Most AC commands in the ECU will just compensate for the additional load of the compressor kicking on, they don't generally idle up any higher than normal.

could also use an rpm switch (like for nitrous).
