Hi wondering if anyone could help me out. I recently changed out my stock lt1 tail lights for ls1 style tail lights and got the ls1 harness to go with it. I plugged in the new harness with the new ls style lights and everything seemed to work fine until I checked my brake lights and the amber turn signal section light up. I'm wondering is there something I'm missing with the swap or a wire that needs to be moved? Any help would greatly be appreciated. I can send pictures to better clearify what is going on. Thanks again!
