I had a quick look at the Shoe Box website and the PDF for this unit.
I didn't see installation instructions but looking at van-cafe and Shoe Box,
it appears that a known good ECU is supplied with the 'ready to go'
monitor.

I swear I recall that some folks might've soldered the Shoe Box
connector wires to
existing wires at ECU connector. But looking at this Digijet ECU image:

I can see how those pins would be more forgiving in terms of soldering
new wires on.

As to my earlier speculation on what the monitor does, from the PDF:

"Basics
It is important to keep in mind as you are using this System as a
troubleshooting tool, the monitor and ECU simply allow the user to
monitor input and output signals at the ECU......"

So it measures inputs AND outputs.

I'd suggest that for an experienced hard core enthusiast or mechanic,
this tool would be
a really useful time saver.
