So with the sniper efi there is 2 wires that you have to connect for a/c, does anyone know where to wire those 2 wires to?

“A” is a ground input telling the ecm to increase the iac to compensate for the compressor load. You would need to use the 12v supply to the compressor clutch to close a 5 pin relay. Then supply a ground to pin 30 and connect lead “A” to pin 87.

“E” is used for engines reaching high enough rpms that compressor clutch need to release to prevent damage. Im pretty sure thats above 6,500 rpm.
