I wasn't trying to be obtuse, I did read that you do not have A/C. But since you mentioned the compressor was controlled by the VA computer, I was hoping you had some knowledge of that.
I have been studying this and I can see how to incorporate the PWM with the fans and my Holley HP, but not the A/C. One way I came up with to speed up the fans when the A/C comes on, is to use have the signal from the trinary switch go to a relay to shift the power to the fans from the PWM to a constant 12 volts for the duration of the higher pressure seen by the trinary switch. I would rather have it all go through the PWM but I don't believe I have enough I/O's with my HP to do this. Again, thanks for your input. Larry
