PCM help and monitoring water temp and oil pressure

[derotoreut]

I'm doing a 5.3L LM7 swap into my '70 K10. My PCM harness is installed and I'm getting ready to start my AAW harness install. I'm quite intimidated by all of this and apologize in advance if any of these questions seem silly or trivial.

There is a water temp sensor in the driver side head that is connected into the PCM. I assume the PCM uses the signal from this sensor to control the operation of my dual fans right? Anything else? So if I want to get a water temperature reading into my Dakota Digital gauges do I have to install another temp sender? Same for oil pressure? The DD kit has these senders included. Isn't it also possible to do some of this monitoring by installing another BIM module?
