Product Description

 

We have a module that will send the AC request signal to the E38 ECU and will allow you to run your A/C from the factory ECU.

Simply  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. 

We have tested this with the truck and camaro calibration. 

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 function if you are running a GMPP GM Performance ECU or calibration. The GMPP calibrations do not have provisions for AC control ***

*** 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. ***
