Dodge D100 Tail Light Wiring

My high school vehicle was a '62 D100 short box 1/2 ton Utiline with a warmed over 318 poly in it. Loved that truck. wish I had it now.

That's what mine is...but with the 225. Still cool to me, but it was designed around a shorter person. I'm having the seats done over and hoping that we'll find another inch or two
