FalconFour, just assembling my bundle of wires. Just wish to confirm that the 3 green ground wires (body harness side) are all connected mid harness according to the wiring diagram and therefore it does not matter which green goes in pins 14, 18, & 19?Oof. Well, I had the opportunity to assemble A Bundle of Wires into the connectors tonight, and... wow! I really should provide more instructions. I made 2 mistakes in the first 5 minutesThankfully, a male pin from the set works great as a release tool (fully and CAREFULLY push it into the release hole above the connector hole, at the connector side, not the wire side). Just be careful not to put angled pressure on it such that it collapses the crimp you're using. It's a bit tricky.
Just... let me help you make fewer mistakes here. haha

Retrofit CCS compatibility onto earlier (NA) Model 3 - DIY approach

Right, the greens go to whatever's clever, no particular order as long as they're supposed to be greens (grounds).
Let us know how it turns out
Thank you FalconFour, the connector is all done and looking sweet. A big shout out to you on the detailed wire work and all your research. My big fat fingers have trouble with the fine crimping; when I was on the bench 25 years ago, wires and connectors were biggerRight, the greens go to whatever's clever, no particular order as long as they're supposed to be greens (grounds).

. Now I have to find me a CCS1 adapter for my M3....
I later test my GEN3 CP ECU retrofit with CCS2/TPC adapter in Taiwan. Three SCs were tested, one Tesla CCS2 V2 and V3 SC, and one third-party (TAIL) CCS2 SC (the equipment is from Delta Co.Ltd). Three different CCS2 SCs are all work very well.
Now for the people interested in this retrofit, the major difficulty is how to get a CP ECU and a high quality CCS1 or CCS2/TPC adapter.
Any one who is willing to sell me a GEN4 CP ECU 1537264-00-B, please contact with me.

Adapter you have will NOT work with this ECU version over CCS2.
You need 20-B or adapter modifications.
Additionally, you need another (newer car) for this test. Yours will not drive after the update.
Just chatted with @AlexUA to confirm what he want to say. He confirmed that GEN3 car can use GEN4 CP ECU with @FalconFour 's mysterious kit, should be no problem.
It looks like the EU Gen4 part number is 1537264-20-B from the info I've been able to find. (1537264 is the Gen4 base part number, and 20 seems to be the variation for EU)
Every Tesla owner should have access to the parts catalog at epc.tesla.com (just sign in normally), and from there you can browse through to Catalogs->pick your car->High Voltage System->Charge System Inlet->click the diagram->take a look
(keep in mind I can only say this works for NA cars... there are no EU cars/stations here to test with! And so far, I've heard that the EU version doesn't _quite_ match up properly... with EU, why would you need it anyway since y'all get the fancy native CCS port already? haha. Legit wondering why anyone with EU plug would need Gen3->Gen4 swap!)

dumb question--but if I have a 2021 Model 3 LR (made in 9/2021); and it just says "CCS not installed" --i can literally swap the part with unstripped version, do a "software update" and it should work right? no error messages, no weird other stuff..etc etc?

Has anyone been able to test thermal throttling on V2 and V3 superchargers in the heat of summer with this retro-fit done? I kinda worry about the values in that thermistor causing some issues when its hot outside and you're. doing a superchare session at full speeds (low SoC pulling 250kw for the bulk till 40%, etc).
I've not yet tested Supercharging in the summer heat, but yesterday may have been a good day for Supercharger testing (at around 90f).
Instead, I ended up at a newly built CCS station with my EVHub adapter, pulling 190kW for a reasonable time. Supercharging seems to stay fairly cooler (thus faster) than using the CCS adapter (keeping in mind that my adapter is an older revision as well). For what it's worth, at least
