Looking for Headlight buzzer schematic diagram

[toadstool]

1970 Barracuda.

I have the road lamp harness. It has the (2) provisions to connect to the headlight buzzer system that I do not have. I'm wondering if this is a separate harness or too difficult to create if it was not there originally. I have not see a good schematic that captures the headlight buzzer. I found something online that is similar to what I am looking for. I dont think I have the headlight connections currently in place nor and buzzer (I think some folks may call this a relay) There are just a couple of connectors hanging off the road lamp relay that maybe would be fun to actually use.

If it is easy I may try to add this. If it is tougher I may just pass.
