FWIW, I was able to finally fit the frunk. It's a matter of contacting Hansshow support via whatsapp, adjust the time zones, but they were very helpful guiding me along the installation (whatsapp video call).
At first I was fearing the struts installation was the cause of the problem. I got on the phone with them and confirmed the struts were fine. Hansshow did mention I did not put all the screws in the strut support frame so took me some time to get my hands on the driver side.
at one time we decided it was best to isloate emergency release cable that hooks onto the Tesla lock, so that was taken out during the alignment
We went through almost an hour of diagnostic and troubleshooting, and guided me aligning the latching mechanism. The support staff in China was patient and actually called me back after his lunch hour and check on me.
Overall, the instructions were confusing, that was a given. Looking at youtube video installs never really address the elephant in the room, replacing the strut on the driver's side. The opening is small and even if you got your arms around it, it was hard to provide leverage as you need some force to snap in the strut to the bracket. The passenger side strut TOOK ME OVER TWO HOURS. Once they were in, plan additional time for alignment.
here are some installation takeaways
1. Hansshow piggy back piece contains a plastic flap, once the hook lowers enough, it hits the plastic flap and in turns triggers the latching switch from your tesla latch. adjust Hansshow piggy back piece upwards so the Frunk hook has a better chance trigger the plastic flap and hit the switch.
2. Align the original latch EXACTLY where the frunk hook will land. There is a V plastic alignment pattern on the Y, you'd want to align the original lock to the middle of the V
3. you will know if the frunk hook drops low enough to hit the Hansshow plastic flap. if it doesn't trigger the Tesla latch, then adjust the Hansshow piggy piece UPWARDS.
4. If it triggers the latching mechanism but not catching the Frunk Hook, you'll spend some time to adjust lateral movement of the Tesla latching piece.
5. if you activate the trigger and the latch locks without hooking the frunk, DO NOT pull your hood up. The device believes your frunk is closed and if you pull the frunk up you'll need to reset it by unplugging the power to the main computer unit. (of course it's not on the installation guide)+
