Im not sure how different the trunk lights can be, its only 2 wires. I took a photo of my rear light connector from Hanshow v3, see if this matches yours.
Apologies ... my confusion regarding the trunk lights was because I'm a noob .
This is the CANBUS OBD cable.

CANBUS-to-control box cable.

The CANBUS OBD cable has 2 small sockets, however, CANBUS-to-control box cable has only one plug (which fits into either socket). I assume one of the sockets isn't used. There are no V4 installation guide on the Hansshow web site. The only references I have are 3 tiny photos on the printed IG included in the box. They show where the CAN/OBD plug goes (bottom of centre console in front of the back seat), and another photo (Trunk wiring diagram 03) shows how to run the CANBUS cable to the controller box. I'm hesitant to post scans of these photos in case I violate Hansshow's copyright. I reckon the cable would go behind the right rear door's bottom trim and beneath the rear floor mat to the OBD port in the centre console.
Another confusing thing for me are these 2 sets of 5 bare wires. The first set is connected to the main harness.

The 2nd set is connected to the Motor Plug and Handle Plug.

I think these two sets of bare wires are meant to be connected together using electrical tape . I suspect the Motor & Handle plugs are separated from the main harness because the cable needs to be threaded thru the rubber tubing together with the tailgate button cable. For those who's received the V4 kit, Step 17 (Trunk wiring diagram 01) and Step 18 (Trunk wiring diagram 02) show the the Motor & Handle plugs connected to plugs behind the trunk interior panel. They seem to replace the V3 Tailgate Signal plug that's plugged to the port at the rear deck (see Step 15 of the V3 IG).
I've also used a metal pick to detach the tailgate button plug from the wires.

The Hansshow provided fish tape should hopefully make it easy to thread the tailgate button+motor plug+handle plug wires thru the rubber tubing.
My V4 kit includes the foot sensor. According to the Hansshow foot sensor IG, you can install it outside (yuk!) or inside. That's next on my research list before I actually take the plunge and do the whole install.
Oh yes ... only after working out what tools and/or parts I need to make the job easier.
Anyone who's done a V4 power tailgate install, please comment if any of my observations above are incorrect.
I am totally confused. Last month I purchased V3 and stayed away from systems connecting to the CAN buss because I read in forums at least two dyi installers were concerned about voiding the Tesla Warranty. This warranty issue was further reiterated by Cici (of Hansshow Guangzhou China) on May 18th. She wrote :
“Hi Sir. This is Cici, I got your email that you need our automatic trunk liftgate for your Model 3
Me: I read about Tesla warranty issues if the powered lift gate is installed. One major contributor on YouTube with excellent installation videos had to remove his power lift gate because of a problem with the Tesla warranty.
Cici: That must not our products. Our tailgate is plug and pay version. Not need to connect CAN bus. Not destruction for the the car. Tesla offer 's tailgate need to connect CAN bus which bus easy to broke the car.”
So now they are reversing their concern and caution, they are connecting to the CAN buss? They mention false triggering with prior versions (V3 and before) . Has anyone experienced this? I read about a concern that something on the road might trigger the liftgate foot sensor but my understanding was that if the car was in motion, the liftgate could not be released accidentally. Is this correct?
Have you installed?Just got the kit myself few weeks back. I not sure what the canbus cables add to functionality...but they mention this one is safer?... Are they saying the old ones aren't safe? Lol
William (@Hansshow) sent me a V4 installation guide PDF via WhatsApp. He said they'll release a new V4 installation video tomorrow night on their youtube channel .
Anyone knows the easiest way to identify the version of the kit? I got both the frunk and trunk back in April but have not had a chance to install them...I think I have the V2 Frunk and the V3 Trunk but just want to be sure.
Also a few questions:
1. Has anyone noticed potential safety issues with the V3 kit without the CAN BUS connection? I thought one of the biggest selling point of Hansshow's kit is that it does not interfere with the CAN but now they are walking in the opposite direction?
2. With the V3 kit, is it still able to wire everything up inside the trunk trim through the rubber tube instead of ripping interior of the car up?
3. To those that had there 12 V power cable wired in the passenger side foot well, any problems so far? I hate to drill through the firewall to connect to the battery if I don't have to but it seems like pretty much everyone on Youtube chose that route...
Thanks!!

I got the V4 Trunk Kit, & I’ve plugged in the OBD/CAN cabling. I can’t see the it does anything differently than without. Also, not sure why the harness has two small plugs, but we only have one connection coming from the controller. Maybe it’s the same harness for Trunk + Frunk??Just got the kit myself few weeks back.

Yes those wires are connected inside the trunk trim now. I believe they reversed it due to difficulty installation many people have. Now that they are pre-cut it is not difficult to fish the wire up with the provide wire. You would need some some sort of lubricant to make it easier.2.

You can also connect it to the rear passenger seat for 12v power. I went that route, no problem so far.3.

Anyway, can anyone speak to the advantage of using the OBD/CAN Harness and how to make it add whatever benefit it’s suppose to add? Like I said, I don’t find any difference.
Thanks,

I think it reduces the chance of the foot sensor trying to trigger whilst the vehicle is in motion as it can read speed, driving mode etc. That’s what Hansshow said on WhatsApp anyway!
Interesting... I went ahead and left it plugged in. It’s easy enough to unplug if something starts to act strangely.
I’d also recommend using the 12v Power and Ground tap under the rear passenger seat. It’s super clean and easy to do it this way. I removed the side piece (bolster) of the seat to run the power and OBD/CAN cables fully behind. It’s a cleaner install but be careful with some of its built in clips, they are fragile.

No. They are competitors with different products as I posted just a few posts before yours. Here it is again: Model 3 Electric Tailgate - Tesla Offer V2 vs CompetitorsExcuse my ignorance, but isn’t Tesla Offer simply a reseller of Hansshow products?
