Question:

Hi, I ordered and installed the kit for my 2019 Tesla Model 3, ran for couple of months and realize left turn light not working, left light always keep on, no bland. Right light is working fine. My question is, how to wire the left light? I watched video on your website, but it’s so confusing, there are 3 wire to connect, and there are 4 wires on light: red, grey, purple, white, how to connect? Thank you

The signal wire you need to use for the left turn circuit of the # 119250KIT that you referenced is a purple wire. The red is the running light circuit. On the right had side the blinker circuit is red and yellow is running lights.

I attached link to the mentioned install video as well.
