Electric cooling fan for a truck

As I understand, a truck PCM doesn't have the hardware to run a cooling fan. If I use a Mustang PCM, will it be able to work with CHT and the IMTV?

no, they dont have the hardware.
why not use the fan on another pin thats unused?
or why not just use the original ecu ?

Original PCM is MPC-204 that won't run FBGI0. Currently using MPC-141 from a pickup.
Using an unused pin sounds way fun. Is it as simple as finding a pin assignment in a fan control subroutine and changing that or is it more along the lines of the fox body fan write up?

why not just use the original tasc3 strategy then?
yeah you also have to make aure that pin isnt being triggered anywhere else too.

Haha, that would be rad if I were defining strategies. Considering my place on the learning curve, I bet I could whip it out something tune-able in 3 years, lol. Reassigning a pin without a bunch of hand holding would be a big win for me.
