So my type s tl. I install a aftermarket radio. And now my parking lights don’t work. What did I do wrong. I checked every fuse. Someone. Please pass some info along. I do have a aftermarket alarm with auto start with the stock remote. The light work when I auto start the tl. But die when I press the brake. Shifter light. Dash lights and ac not lit as well. I checked every fuse. Both sides and under the hood

 

Fuse #59 (15A) under hood fuse/relay box. Tail light relay could be a culprit also.

Since you were messing with the audio, check the red/blk wire that it's not grounded.

 

Did your aftermarket radio come with a reverse camera? It sounds like a wiring issue to me.
