This post is to thank all the folks that contributed to this thread over the past several months – A BIG THANK YOU! Your free sharing of thoughts, ideas and experiences, made my installation of the Hansshow trunk powerlift (relatively) easy and stress-free! I have tried to summarize my experience with the install and hope it will help others that plan to tackle this project!
I direct ordered the kit from Hansshow using a discount code from Model3Man to knock $75 off the price. I did not order the foot switch. The elapsed time from order to delivery was approximately 12 days. They ship out of a warehouse in Singapore using DHL. There was total silence from Hansshow after receiving the order confirmation via email. Multiple WhatsApp nudges later, they finally sent me the tracking number via WA.
It was Version 3 kit, which is a great improvement over what I have seen in several YouTube videos. It included a wire fishing tool, a trim removal tool, and the wires to trunk latch switches were left cut to ease the movement of the wires through the rubber tubing. I also removed the plug for the lid actuator switch to make things easier (see YouTube videos). Pulling the wire harnesses through the rubber hose was so very easy. Used glass cleaner spray can to lubricate the wires (does not leave residue after drying). It worked extremely well! You will have to buy some solder seal wire connectors from Amazon. They work well with a BBQ gas lighter torch.
The YouTube videos that I particularly liked and utilized were posted by Model3Man, ElectrifiedGarage and BecauseTesla. Thanks guys!
I avoided removing the bumper to route the strut cables and instead used the hole behind the tail light fixtures (after making a drip loop). Worked well, easy too, and tested with a garden hose to make sure no water would enter the trunk.
Attached the ground wire on the left side (opposite subwoofer side), as it was easy to get too and less cluttered. The 12V+ line was routed behind the right trunk trim and under the rear seat cushion. There is a 12V+ post that’s easy to access underneath (see ElectrifiedGarage video).
The instructions that come with the kit are really sad. Even the wiring diagrams were incorrect – they were for an earlier version of this kit. Fortunately, someone posted the correct diagrams on this thread – it was INVALUABLE! Thanks.
It took me about 6 hours to do the total install and clean up. It could have been a lot faster, but was slowed down by my aborted attempt to route the power strut cables behind the bumper. Also, reinstalling some of the trim took me longer than expected.
If you are planning to install this kit, I strongly suggest you watch several videos on YouTube and read all 6 pages of this thread. Become familiar with the multiplicity of wire routing options, and become comfortable with it before you embark on this install journey.
Bottom Line: The install went without a hitch. The power lift works as advertised and I LOVE IT!! Bonus – if you use the STATS app on your iPhone and own an iWatch, you will be able to control the trunk lid from you watch using SIRI!! How cool is that!
