I understand this is more complicated than just wiring it up ,,, but are there any E67 set ups that use a terminal (powered or grounded) for A/C on request?
So far, every wiring diagram I find has the request for the A/C clutch coming down class 2 serial data lines.
I am trying to have the E67 control the clutch in an older car without resorting to an HVAC "upgrade"
The car currently just has "on or off" power from the control
Thanks for any help
