Based on what I've been reading, it seems like it was a bad idea to install this harness then since it lowers the resistance of the speakers so much, and I doubt the amplifier is rated to run at 1.2 ohms as @todd2fst4u stated above. I am worried about long term damage to the amp now. That's too bad as I really like the sound quality. Unless anyone knows a way to add an amplifier to the install, I might have to remove it.

Hansshow Audio Upgrade? (SR+)

Probably not a good idea to run the system at max volume for extended periods but moderate volume levels are probably fine. So far I haven't heard anyone reporting a blown amp (knock on wood). Guess people will have to decide if they prefer the sound of the untouched system and be able too crank volume to max OR have the extra speakers with moderate volume. I'm guessing the latter is better giving better staging and fuller sound.
I've noticed with this harness that I only need to run the volume at 60% to 70%. Previously I was putting it as high as 85% to 90%. If it's fine to run the speakers at a lower resistance than the amp as long as volume isn't high (I don't think 70% constitutes as "high"), then maybe I'll leave it plugged in...

Yes, both suppliers have shipped harnesses with reversed left and right channels for the rear speakers. I haven’t compared the sound quality personally because I don’t install them as-is. I just cut off their connectors to use on my own harness. They would sound the same as each other as they are both fundamentally the same.
You buy the modified harness from @todd2fst4u which has connectors to a 4 channel amp and a mono amp
That isn't exactly true. The hansshow diy harness has 4 high pass filters in their little box. I haven't verified this, but my guess is those filters are for the 4 additional front tweeters. Depending on the cutoff frequency they chose, it may limit frequencies sent to those tweeters that would otherwise be heard from the teslaoffer harness.
But it is also possible that the cutoff frequency is below the crossover in the ice and there is nothing to filter anyway. Anything is possible with hansshow.
If Hansshow had properly spec'd crossovers that were subject to good R&D and testing, then maybe it would be better. Problem is, it seems there has been a consistent significant myriad of problems with their audio products. Also, if the speaker tapped for the signal already has the lows cut-off at the ICE then adding a crossover might be redundant.

Yes the photo is outdated. It also shows a driver footwell connector instead of the B-pillar connector they are actually shipping.sorry. that wasn't shown in the pictures on their website.
then yep, they probably sound the same.

Correct. Both of the A-pillar speakers and the driver side mirror tweeter connections can be accessed at the B-pillar blue connector.

He is just trying to show how to remove the kick panel in that clip. I agree, it’s a bit confusing because he switches to the other side of the car in the next clip. There are some small differences between right hand drive and left hand drive in these areas.
Installed the DIY harness in a May 2019 build. Ordered a few weeks ago and received it very quickly. It was pretty easy to install. Sound is much fuller, and I did not notice a degradation in bass. Overall I am very happy with the sound.
My only concern is the health of the system longterm. Definitely do not want to overload base system/amp... How worried should I be about this?

There’s some good information here about the importance of speaker impedance
Series Parallel Speaker Impedance
Series Parallel Speaker Impedance
I find that when I set the volume around 30-40 percent the sound is plenty loud but that is just me. I wouldn’t think that would have any affect on the system long term. If you want volumes >50 percent they you might be asking for trouble.
