Okay. That helps. So, what we need to do is unplug the things that the control module feeds.
So, if one of these are shorted then that will cause the fuse to blow as well.
When you unplug the control module then you are eliminating the short as well but if that was replaced then clearly it wasn't the module.
I would start with the transmission range sensor and then the transfer case shift motor.
I attached the diagram below again with these circuits highlighted.
If this still causes the fuse to blow when they are unplugged, then we need to start checking for each circuit and a short to ground.
To do that, we remove the control module connector and check the resistance for each circuit to ground. They should all be open circuits or OL on the meter except for the ground circuit.
So, you use your red meter lead on the terminals of the connector and the black on a known good ground like a bolt on the frame rail.
