Making a engine wiring harness

This. And there may be a 16-32 week lead time. And they will also probably tell you that those part numbers don't exist (if they're proprietary OEM).

With Sumitomo I had to have a company tax ID to order them. The quoted lead time was 16-32 weeks, but they ended up getting them to me in less than 4 weeks.

I don't want all that hassle, I will simply buy the pre-crimped wires from Toyota anyways...

By the way, for soldering my harness, I have 2 type of solder wire at home. Which one is better?

1. Dura pure 95% Tin 5% Antimony
2. Rosin Core 60% Tin 40% Lead

Thanks

Lead based solder tends to flow better, but for environmental and health reasons has been replaced by the tin/antimony blends. I personally would use the lead for what you are doing.

That's always a bonus. In our engineering department, we have to beg/plead/steal to get enough of them to do the development testing of our shifters (assuming that we lost our minds and went with a new connector) and normally end up behind schedule as a result of someone not anticipating the lead time.
