From what I can tell . Large black wire should be pink/blk tracer this wire goes thru firewall connector to the ignition switch probably been spliced at some time in past. Dark green is power to the horn. Small black wire goes to horn button. The reds go to the battery the alternator and the head light switch.

the blk/pnk wire goes on that connector from the ignition switch. thats what makes the buzzing sound when you open the door and leave the key in the ignition.

This exact question has come up before.

The Chassis Service Manual is very clear on this.
The scan below is from the CSM in WildAboutCars (I gave away my last hard copy with my last '68 Olds), but it should show it clearly enough.
