Ok, did my install on my V3 Frunk from Hansshow today (and I have the Foot Sensor but didn't install it, I'll explain why).
To Start I used this video
Great walkthrough with a few differences with V3.
1. It comes with the rubber pouch which .. is kinda a pain to get the control box in there.
2. There is only 1 gray plug that comes off the soft open/close. It still works fine only plugging in the 1.
3. Mine did not have most of the cables labeled in English at all. Still easy enough to figure out what plugs where
4. On the newer one I got, the plug that goes into the Front button (the button inside the frunk) is only used during setup. After that, you unplug it and just plug the front button back directly into the factory cable. If you don't, the frunk will auto open every 8 seconds. I have no idea why this is different unless it's something to program the unit to the OEM electronics. BTW that front button plug is a pain in the butt to get the wire unsnapped.
5. Programming mode i believe requires the front button cable to be connected, so if you want to adjust the speed of it, do it BEFORE you put everything back in place. Just holding the front button doesn't trigger the programming mode like the instruction say.
Other than that: this video gave me a really easy walkthrough and it worked like a charm. I can't remember any other differences.
Now on to the foot sensor. There were ZERO instructions in the box of what to do but I found this video which is a good install video
Seems super simple. Though in reading the comments here is a very important note. I don't know if this is common knowledge but it wasn't to me so I'll post it.
THE CAR MUST BE FULLY UNLOCKED FOR THE FOOT SENSOR TO WORK.
That means, it won't trigger unless the mirrors are fully folded out. Just being near it with your Key Fob/Phone doesn't all the foot sensor to work. You will need to open your door to fully unlock it before the foot sensor works.
I have a Keyfob that i bought which means there is almost zero benefit to having the foot sensor as I would need to get a hand free to unlock the key via the keyfob or door anyways. Might as well just double tap the key fob to open the frunk (which WILL open it even if the car is locked). So just a word of warning that as of right now, that's the only way it works. For me it wasn't worth installing then. I can't ever see it being useful to me (with a Keyfob). For someone that just uses their phone, it might still help but isn't as straightforward as just walking up and waving your foot.
I'll probably end up just selling the foot sensor (if anyone is interested in it, let me know).
Overall: V3 works great as intended. Keyfob opens and closes. App opens and closes. Screen opens and closes. It took me maybe 2 hours to do all of it and that was with me taking my time and watching the video. Could easily be done in 30-45 minutes if someone already knew what they were doing. I'll definitely be using my frunk way more often now.
