This has been a bit of a slow time working on the truck because of family circumstances and other events.
I was able to get some more work done on the lights (blinker lights). First I installed separate indicators instead of piggy backing on the main tail lights. I installed a new cutoff relay and was able to trace the wires inside the cabin to the outside.
After a few tries using a troubleshooting light I had the left side front and back working. The right side was also debugged except the lights will not blink.
I also received the spindles in which will be major work. I will post more soon.
