Hansshow Audio Upgrade? (SR+)


New Member
Apr 28, 2021
I ordered and received the Hansshow wire harness for my 2021 Model 3 SR+. Going to try and install it this afternoon. According to the instructions, the two loose wires should plug in to an existing plug.

I’ll update my findings shortly. Hopefully your issue with Hansshow works out. It took nearly three weeks via FedEx to receive my order as Hansshow ships directly out of China.
Hello there,
Have you been able to install the kit? If yea,
Could you let us know what your feedback is?

Ordered a version F a week ago for 2021 Model 2 SR+ . I have not yet received the shipping email.

Does anyone know how much time it takes to ship after ordering?

I installed their kit for a 2020 Model 3 SR+ as well, and the results on my 2021 SR+ were on par.

I would recommend plugging everything in first before running your wires through the center console to test the audio first.

The only difference from the pre-2021 update is the missing front signal plugs (previously a more square shaped plug, and has been replaced by a red and black wire for each side of the vehicle. The instructions specify which wires to plug into. They share the same existing wire and for driver’s side, you match the black with black wire, and red with purple wire. For the passenger side, you just have to match the red with red wire, and black with white wire. Once everything was tested, I ran the wires under the carpet along the dip in the floor. There is enough of a gap beneath the carpet to not feel the wires through the carpet.

As expected, the front tweeters and mids were activated and produces audio that feels more immersive than the speakers closer to the windshield and in the door. The rear deck is missing speakers, although I connected the harness to it so the wiring was complete and neater. (No adverse effects as a result) I tested the left to right channels in the audio settings and everything was correctly functioning.

Shipping took about three weeks to reach me in Hawaii. It did travel to the continental US before heading back to Hawaii.

I had the Version F installed this week. I'm not an audiophile by any means but even I could not stand the original Tesla non-Premium setup, and of course now the sound is definitely significantly improved (as it should be, considering the cost of the upgrade!).

My question to anyone else with Version F: Where are you supposed to put the remote and the USB cable? Just hanging out (seems really unfinished) or do you just tuck them in somewhere? I don't think I will be fiddling with either i.e., probably just set it and forget it.

Hey @badiban - did you have trouble getting the big plug it of the computer when you swapped cables for the F kit? Got someone struggling here- is there a secret?

That part was tough. I have big hands so it was tough to squeeze into that area to remove the old DIY cables. What I did was I carefully wedged a small flathead screwdriver so that I can press the latch with it. Then, with the other hand, once you're able to firmly press on the latch with the screwdriver, you should be able to pull the cable out. It's hard, but possible.
