Hi guys,
this is my first post here. So please be patient if my pics don't show up

I'm putting my Charger back together. It was a 318 and I'm building an R/T clone. Has a 440 and 727 TF(floor shift) w/ 8 3/4 rear end.
Right know I'm working on the wiring and can't seem to figure out where one connector goes.
I have 4 connectors coming out of the steering column

The two eight prong, the ignition switch light and a 3-prong.

Anybody know where that 3-prong goes?
As I said, it was a 318 and the previous owner swapped a 727 in. Maybe some remainder from the old tranny configuration and a different column?
The wire colors seem to be Tan w/ white leader, pink and light green! Couldn't find anything in the wiring diagram....
Thanks guys!
Tom
