Looks like what I need but....the relationship between the 85 terminal and the 30 terminal. Is it saying I need to jumper the two terminals?

Yes, although you could power each one separately from different circuits.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.

The relay is a Bosch relay. The attached is similar to Rusty Rod's diagram, but shows the internals of the relay. don

Hooked everything up per all the info I got and the horn continually sounds. Figured if was something in the steering column. Took it apart and stripped it. The horn still sounds! WTH?
