    Sorry, you lost me after "After". That's an old modern truck, electrical gremlins will drive you nuts. I say this everytime with older trucks, start with a good ground to the cab. Bad grounds do all kinds of funky things. I drove a '99 Century for a friend, it was a nice truck, but had almost 900 grand, and was beginning to do the same stuff. Good luck.

    Parking brake switch is normally on the back of the brake valves. Check switch with ohm meter, check voltage as well.
