Joker,
What a great wiring diagram. Very clear and concise. I wonder why it indicates it is for '47-'53 AD trucks, buts lists the tailight lamps as being #1157.
I have been jabbering on another thread about lamps/bulbs, and I recognize this as a 12 volt unit.
Weren't all the AD trucks 6 volt until 1955. Maybe it was a typo on the authors part.
