Hi guys, long time no see.

My sequential taillights are acting up on one side. I bought the plug and play (no splice) harnesses from either Classic Design Concepts or AM a few years ago, can't remember which, but the right side light will not light up sequentially anymore.

All three sectors will light up normal, at the same time, or else the two outer ones will light up normally ('normal' meaning as a stock 2005-09's taillights would).

The left taillight still lights up properly in...

Help with sequential taillight problem
