To command the PCM to enable a/c idle tables when the clutch cycles to on? 04 PCM with LQ4. Idle was still somewhat stable during clutch cycle after engine swap, after cam, heads, exhaust, gears, stall, etc... not so much. Will the a/c lines have to have a pressure switch fitted to them or just a simple on/off signal?

Either way, which PCM pins need to be utilized for this function? Its a Blue/Green PCM.
