Product Description
We have a module that will send the AC request signal to the E92 ECU and will allow you to run your A/C from the factory ECU.
Simply hard wire it into your harness and when you apply 12 volts (Positive control) or Ground (Negative control) to the trigger wire it will send the AC request signal to the GM ECU.
If your AC unit outputs 12 volts when turned on you will need a postitive control box.
If your AC unit grounds the output you will need a negative control box.
*** This will not work corectly if you are still running a GM BCM in the system. The BCM will be sending the Ac request = OFF message and will make the AC request jump in and out when our module sends a AC request = ON message. ***
