Default will 4x4 work without ecu in the car ?

Just wondering if the 4x4 system will still work if there is no ecu in the truck or if the ecu in not getting any data from engine / transmission


Doing a engine swap and and would like to know if i should switch to a manual transfer case or if i can keep my original electronic one.

Truck is a new body 2007 sierra 1500 with 4wd auto mode option.
