So, quick update. I reconfigured the inside of the new lights to reflect the wiring schematic in the old lights. Wasn't hard to do, just took some time. I only did one light to see if there was a difference but it didn't change anything. Both of the lenses work as needed but the dash is throwing me the lights telling me they don't like what's going on back there. My next thought is to try the old bulbs to see if that makes a difference.
I had to rebuild the rear end so this hasn't been much of a priority since they do work.
