I am sure you can do something similar in the 80.
supposedly the vortec pcm will sense the drag from the compressor and self compensate the idle. There is an input to tell the pcm the a/c is on but it's a CAN input from the body module on the gm truck so no dice trying to make the toyota a/c amplifier tell the pcm the a/c is on. I will have an input to the fan relay set to trigger a small pusher fan mounted in front of the condenser to help with low speed a/c performance.
