98 silverado electric fan upgrade

99 Silverado with a clutch fan.
We found a newer suburban parts truck with dual electric fans.
do I just need an aftermarket wiring harness to make this work?

The harnesses I have found say it plugs into the PCM. Will the PCM recognize this on a truck that never had electric fans?
FWIW, I'm a carburetor guy, this is for a buddy's truck. I have no idea how to wire components into a confuser controlled vehicle. I could wire it completely separate from the PCM, but I ain't sure the truck would like that.

Usually in the old truck section
