Power to the relay is on the Yel/Blk wires (2)
PGM-FI Control is on the Red/Blu wire.
The Switched terminal is the Red wire. This goes directly to the Thermal Protection built into the compressor.
With the gauges connected and the vehicle running, jump either of the Yel/Blk wires to the Red and the system should operate. Avoid leaving this jumper in and keep it from grounds.
Remember the compressor has built-in Thermal protection, and that may be going open.
