Hello all,
I am trying to retrofit an L33 into a vehicle where the HVAC control head sends a 12V compressor request signal to the PCM.
Does the P59 PCM (Blue & Green) have the ability to accept a 12V compressor request? It is currently setup to support a serial request, and I can't find any pins that would allow the use of a 12V input for request.
I'm hoping that I'm just overlooking something. Would be nice to have compressor control through the PCM without having to add a custom controller.
Thanks,
-B
