Shout out to @Lotus for helping guide me!
If you have one of those eBay / china tucked harnesses and are not getting spark and or your radiator fan turns on after cranking then you need to swap pins 7 and 20 at the C101 connector. I also recommend buying a quality solid ground lug for 16ga wire with a 5/16 hole and replacing the ring terminal on the harness.

Thanks for the feedback on that guys. The harness looks quality-wise a bit questionable. What is the wire size and insulation specification of these? Any idea?

It's not great but it's not bad. Only thing that feels cheap is the wire insulation and the braided loom. Looks like 16 or 18ga wire for every pin. It's pure stranded copper.
I had the intention of buying a better harness if need be but this one seems sufficient enough for now. Time will tell if it holds up against many heat cycles and road grime.

• Features: All plugs have gasoline and diesel resistant housings, and all plugs are designed to work in harsh weather and extreme temperatures (-67°F to 320°F).

At the engine OEM, I worked for till 2018, 125 °C insulation resistant material was used. It was not ROHS conform, but could be CE legal because of the argumentation (mass content, use case, safety). You don't find any better material then this. Thence 257 °F is quite a very high temperature value, even for Chinese production, where CE conformation does maybe not count. I have my doubt on the 320 °F, maybe they calculate differently from °C into °F .

Oh yeah. I highly doubt their material holds up to the chemicals and temperatures that they claim. Haha

Can I is it the plug socket what colors I need to know ECT is and have no spark

What?
