Hello german Olds enthusiastic need some help about wiring engine

First of all hello,
my name is Jörg from the north of Germany,
I'm 50 years old and restoring an 1972 Olds Cutlass Supreme.
I have bought it partly disassembled, that's the reason why I need some help because I don't now where some parts have been,
I have bought an 455 engine from 1971 eighty eight and rebuild it.
My plan is to start it soon, therefore I need some infos about some cables.
Ok here are my questions I'm wiring my engine up:

Red circle for what is this relay supposed fore and (i know all 12+ hot wires go in front of it ;-)
green circle wire pink black does it goes into that relay there is one connection left at right side ?

Thank you for your help !!!

Regards Jörg

That's the horn relay, the stud is just a power distribution point.

It's called a horn relay. Get yourself one of these when you get a chance. Welcome, good luck with your project.

The 1973 wiring diagram shows a 20 gauge pink with double black stripes going to the horn relay.

Guten Abend Jorg,
Pink wire to the horn relay is for the buzzer when the key is left in the ignition and the drivers door opens. On the older cars the switch in the steering column is often kaput so you might not get the buzzer even with it plugged in.
