The previous owner of my '99 SC4 put in LED headlights and turn signals. The left front turn signal isn't working. He said it is possibly a connection, however, cannot for the life of me figure out what's stock and what is aftermarket. I'm not concerned at the moment with the headlights, as they work. I do plan to pull all aftermarket and replace eventually with stock. For now, I just don't want to be that A-hole who is turning without a signal.

On the driver's side, I see these lights.



He probably put the amber signal bulb in to ensure correct wiring.






There is this connector set which i don't think go to anything I'm just fearful of connecting them and shorting out something. I would assume red goes to black but am not ready to do this just yet.




Here's the other side, which is working correctly.



I actually contacted him, and he recommended checking the connections. However, it has been a few years so he doesn't remember what goes where.

Thanks in advance!
