I recently wired my 01 s10 for trailer lights and all was fine. I spliced right after the connector for the whole rear light wiring harness. My lights were working perfectly fine until my driver's side turn signal started hyperblinking and I had no break lights on the same side. I crawled under and found nothing wrong with my splices. I hooked 2 different power testers up to the wire and found that I wasnt getting any power to the yellow wire at all. Not even before the splices. My front turn signal is blinking fast but the rear doesn't blink at all. I just had the ground redone and redid it in the process of figuring this out. Any suggestions. Do I have a short somewhere up the line?
