Hello there,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.
Have you been able to install the kit? If yea,
Could you let us know what your feedback is?
