Default Puddle Lights and Red Lights not Working After LED Install

I recently changed the lights in my A4 to LED. I only did the back doors but when i installed the lights they didn’t work, alongside the red warning lights not working. What can I do? I read somewhere that it may be the ECU turning it off? I apologize since I am a noob when it comes to modding. Please help me out and let me know what I can do.

Check the polarity of your connections - LED connections are sensitive to which pin is + and which is -.
