Do you really need the 1nzfe cluster when doing a swap?

Hey Guys.
I know I don't post much on here. I just observe everyone's threads.
A few questions for you guys.
I have many people telling me this and they could be right. I am not here to say they are wrong but want someone to chime in to finalize the question.

If you were to do an engine swap in a small classic micro car (pick whatever one you want), would you absolutely need the cluster for the 1nzfe?
The goal is a classic micro car with a stock 1nzfe. The only thing that would be modified would be the exhaust system and the electrical.
Due to a micro car being so small and limited on space, its hard to stuff all of the electrical system into the car, so aftermarket gauges will be needed and just enough wiring to make the engine run with zero issues or CEL codes.

When doing my vtec mini swap I was able to remove whatever wires i didn't need and be good to go. Will the 1nzfe get angry if i did that?



Thanks
