    E46 LS A/C questions

    In the final stages of LS swapping my E46 and trying to figure out how to get my A/C functional. I have been able to find information regarding how the system works from the factory and have found a few write ups on how to make the system function with a GM PCM, but I am running a Holley Terminator X ECU for engine control with a CAN bus adapter to run the factory guages. The Holley ECU can be configured so that an input can be used as an AC kick, and I can configure an output to control the compressor, but I'm not sure how to set up the system so that it operates correctly and safely.

    Any ideas or suggestions would be great.

    Did you ever find information on this? I will be doing the same thing in the future. I currently run Holley on my LS swapped 64 Nova so I am familiar with Holley Terminator system.
