I have a 2019 Optima S, I am trying to install a set of door warning lights purchased off ebay. I am trying to find the wire attached to the door latch which controls the interior light. I found a yellow wire going to the latch but it turns out to be a constant power and not switched. I need to find the switched wire. I thought the yellow would work but NOPE drained my battery dead. HELP I really want these lights for my door.
