So we got part of the puzzle figured out tonight on the tail lights. We now have the brake lights figured out, which is good. The turn signals are working fine up front, but the rear is not working correctly. When you move the turn stalk to the right both lights come on, and when you turn to the left nothing. So it is either in the turn signal switch or maybe in the flasher relay. Not sure. A very good friend of mine who is a great auto tech came over tonight and patiently went through the wiring diagrams and got us this far. Hopefully soon we will have those gremlins figured out and we can move to other larger items on the list.
