36 pickup dash light switch

[rottenron36]

I took my 36 pickup apart over 8 years ago. Original type wiring, gauges ect. I see on one of the wiring diagrams it shows a dash light switch. I don't remember seeing one or removing one. Did 36 pickups have one, and if so could someone enlighten me, where it is and what it looks like? Thanks Ron P.S. it's finally starting to come together.
