Re: 1990 brake light switch

I found an 1988 schematic in one of my old training manuals from the GM training center in Minneapolis. Here is what it shows.

Pink = Power from Ign
Brown = from brake switch/ clutch switch
Gray = Power when cruise switch on
Dark blue = Set switch
Dark green = Resume/accel
brown w/ white stripe = speed signal input
black w/ white stripe = Ground

If it is modified from what came stock from the factory, let us know that too.
