CCRM looks like more of a wiring nightmare than a benefit.

CCRM has no relays inside, it is just the controller so you still need the relays to turn fan on and off.
You can do it much easier and better(IMO) using other relays and either a Rad temp sensor or Rad hose sensor
This is an article about E-Fans in Rangers: Volvo Electric Cooling Fan
If you are a 4-wheeler you can add a cut-off switch in the cab to disable e-fan when doing higher water crossings, keeps upper engine bay dry.
If you have A/C you can add an activation relay for e-fan when compressor is turned on.
Temp sensor would activate e-fan regardless but the A/C relay gets ahead of the temp increase when using A/C.
