Harness is installed and works well. Only need to lengthen the two control wires and route them to the PCM inside the engine harness. The PCM will be controlling the fans based off coolant temp and a/c pressure. I am adding a GM a/c pressure transducer to the a/c discharge hose between the compressor and condenser. I tested the fans on video. First on low speed with the motors in series for 6 volts each. Then on high speed with the fans in parallel and 12 volts each. Fans draw 9.25 amps on low and 37 amps on high. The startup amperage spike is also very low with this wiring arrangement. The PCM will also run the fans only as much as needed so less wasted energy. With the PCM controlling the fans I can adjust the idle airflow when the fans turn on and off to maintain a steady idle speed. The PCM is also going to control the alternator when I am done with the wiring changes which means stable voltage as the fans turn on and off. I am going to try to bend the trans cooler mounting bracket in toward the condenser to get more airflow through it. It sticks out close over 2" from the condenser now because the condenser is thinner. Even so the airflow through the trans cooler will still pull a paper towel against it on low speed and hold it in place. But with the 2,800 rpm stall converter its hard to go overkill on trans cooling.
