I'm using the 1.8 cvh and used the esc. Its pretty simple to wire it up with the aid of the haynes manual. Then i just built the rest of the
loom around it.
As for if it is needed i couldnt say, i just thought it was easier to use it.
Oh and welcome to the mad house!
HTH,
Chris

Yes you need it.
But it's simple, you should have 3 loom plugs on the engine sub loom.
the following download "loom plugs (Sierra to granada) details the functions on the 3 plugs. It's intended for helping put 24V's in
sierras but should do the trick.

If you are keeping the original carb setup then I would say yes you need it.
That is what I have done, also keeping the air temp sensor mounting it within a Piper cross plate.
If you are going down a bike carbs then would suggest a possible route would be megajolt route with edis4.
Which route are you going?

Why do I have to make the tools to finish the job? More time then money.

I don't see any advantage in replacing the ESC-Hybrid with Megajolt.

Neither did I, that,s why I kept the Esc-Hybrid system on the Sierra Donor with the 1.8.
But a few others on here have fitted bike carbs and say it gives more power, and when they have done so they went Megajolt.
Below is what I learned from the donor I had 1.8 CVH 1991 vintage with Esc-Hybrid.
The Esc-Hybrid system has 4 sensors I think if memory is correct.
Incoming Air temp in the filter, water temp, vacuum via its inbuilt MAP sensor and the 36 :1 wheel position sensor.
It controls vacuum switches for choke and something else?(not sure what unless its two stage choke enrichment), also provides a pulsed relay for the
electrical heating of the choke bi-metal strip and as such is dependent on the auxiliary output from the alternator
I guess going to bike carbs you would loose some of the functionality of the Esc-Hybrid system and as you can not reprogramme it for different
timings dependent on load, extra fuelling etc, it is why they have used Megajolt.
Just a guess, I am no expert on management systems, wish I was.

Good grief my . and , and caps are miles out, I keep reviewing it. (Getting sad).
