Got the standalone pnp but my a/c doesnt work, and it worked great on the stock ecu. Do I have to wire it in? When I press the air condition button nothing happens......

if its connected you will need a pullup resistor to give the ecu a signal. The supra signal just goes from open to ground so the ecu does not get any voltage change to know the button is pushed. you need to find the wire that is connected to the ecu input then add about a 2K resistor from that wire either to a 12v switched power or to the EMU 5v sensor supply.

The pullup is built into the PNP adapter, A/C control just needs to be configured.

On my USA supra Analog #1 comes pre wired for AC and needs to be configured. Someone correct me if a am wrong.
I dont have ac so ill be cutting that wire (blue/something wire) to use that analog in for methanol fail safe.
