I'm installing a Gen IV Vintage Air system in a 1969 Camaro with an LS1 engine. I'm using the three knob controller option. Everything seems to be hooked up correctly. When I connect the main power lines (red and white) wires, the fan comes on immediately, even without the key being on. I tried to calibrate the knobs by turning on the ignition and connecting the programming pin to ground, but the fan just keeps running (seems like high speed) with no change in fan speed. When I change knob positions, still no change in fan speed. Any suggestions? I have not yet charged the system.
