UPDATE:
I'm most of the way there. It's 95*F right now, so I have lost my enthusiasm.
I think the car is driveable as is, but I gotta problem(big surprise)
The brake lights are fine, as well as the parking lights. The left turn signal is fine also. It's when I turn on the right turn signal that things go down the pooper. The right tail light flashes as it should, but there is a ghost like flash on the left tail light as well. It is much dimmer, but noticeable. Also when the right turn signal is on, both the front and back side markers lights flash.
I'm guessing a ground problem, but where? I installed the old 1157 bulbs in their sockets that are just sitting on the bottom of my trunk now. They didn't flash, but they made the ghost flash on the left brighter, so I knew that wasn't the answer. I also installed a couple of the empty sockets back into the tail light housings, but that made no change. I just hope this isn't something on the control board that needs attention because it is sealed in shrink wrap to protect it. I'll also add there is a button on the control board to make these LED lights act without the sequential thing going on. As I suspected, that made no difference.
Since I'm the guinea pig here, I don't expect anyone has gone thru this before, but I'm just telling you where I'm at now. The good news is the original turn signal flasher seems to work fine. Maybe I'll get back at this in a few days...
In the mean time, I made my first You-Tube clip. It's short, but you can see what's going on.
