Holy smokes that’s a lot of wire. Is that from an Express van? They are REALLY long, which gives you plenty to work with.

It looks like you have all you need, now you just need to put it all together. We need to know what it is, and what it’s going into.

The one on the left side is the original S10 and the one on right side is the one came with the Ls engine.

Quoted for being sound advice!
Why even mess with an old harness with brittle wires, crappy loom and dirty connectors? This is one place where you just gotta buy once, cry once. You're inviting a host of issues trying to mod an old harness, IMHO.

Would you please refer to one good place (website) if you don't mind 🙏

As an observation - if that is masking tape being used (temporarily) on the engine, don't leave it on for an extended period. It can become significantly more difficult to remove if left in place too long, sometimes to the point of needing to scrape it off. Blue painter's tape keeps things sealed up just as well, and is much easier to deal with.

And God forbid you use Gorilla Tape anywhere you don't want it forever. After a heat cycle or two, it's bonded for good!

And as was referenced above, Current Performance is the go-to for quality harnesses. If it is going to be a nice show truck, they have looms that'll make it look killer.
