PCM Pin Outs, Can These Be Reprogrammed (Empty Pins)?

[Level2]

I have a 2001 Suburban 2500, 6.0L, 4L80E. I am looking for a pin out to run the high speed e-fans I have installed. Normally, this would be the RED connector, Pin 33. But on this truck, it contains a pin out to operate the RECIRC DOOR.

Obviously, that will not give high speed fan control should the engine temps rise and the low speed fan is not enough.

Can I use an empty pin out and program it to do the high speed fan?

There should be the ability to change the function of that pin, but it's either the recirc or the high speed output. If that's not enough, hardwire a switch to fire the relay.
