Default Stock cooling fans

Drag car only.
Do you let the PCM control them or put them on a manual switch.
If on a manual switch would you run both at the same time.
Would you run them all the time, from the staging lanes all the way back to the pits. Another word, when the car is always cranked.

Would running them all the time, interfere with the PCM doing it's job.

I think that's the way I'm going to wire mine.
Let the PCM do it's job and put in a manual over-ride switch for cooling off the motor in between rounds. Along with the electric water pump.

I think by grounding the Dark Blue and Dark Green wires going to the fan relays will do that.
