Stock PCM/ Hotwire Harness control electric fans?

As the title says, I've got a 6.1L controlled by a stock PCM and tuned using HP tuners. The harness is a Hotwire harness. There's no wire as far as I can tell for fan output. I've got both fans on separate fuse and relays already just need a controller or the PCM to turn them on and off.

Can the PCM do this? Anyone know what pin it'd be?
