What is the difference in the early style harness from the later one?
Location of the compartment light is one difference (main bodies on Non AC bases are difference also) . Can't remember if the very early had an illuminated shifter lens since it didn't have the arrows.
So blue9450 do you need the main wire loom or the pigtail from the compartment light?
Can't recall if I kept any of the wire looms but will look if I know which one you need. Bought and sold allot of these in the 80's Mustang shops didn't want to spend the time cleaning and reassembling these so would by dozens of them from each shop, redo them during the week and sell them on the weekend at swap meets. Always good sellers.
