As warm temperatures have arrived- I'm wanting to get my A/C idle up turned on.
I went into tuner studio- and turned the A/C function on - selected table switch -then low input.
Should this input be set to High? For MSPNP2 ?

Its asking when should the input be active, low or high. Low is switched to ground, I will have to check but I dont believe the tableswitch pin us capable of accepting 12v.

DIYPNP needs a 2N2222 which it has internally but is not wired up.

Relay 1 & 2 circuits are 2N2222 rated at 600 ma which activate the relay coil directly via pin-54 & provide sensing to pin-10.
Pin-10 is used as a sense to determine when the Clutch Cycling Pressure Switch is closed.

MAIN BOARD.......EDGE PIN CONNECTOR NAME.......ECU PIN
Relay1-In to PT6........WAC (WOT A/C Cutoff)
Relay1-Out...............WAC (WOT A/C Cutoff).............54
Used for AC Idle-up
Relay2-In..................ACCS (A/C Cutoff Sense)..........10
Relay2-Out to PA0.....ACCS (A/C Cutoff Sense)
