This is from an original factory 72 service manual in color.
The pink wire to the horn relay is very faint.

The pink wire may have its own plug. Is there an open terminal on the horn relay?

Do you find a pink wire coming off the connector on the steering column?

A photo of this part might allow others with a 72 to compare/confirm

..There is a molded connector located above and in front of the fuse box with 3 wires, 12v, ground and ground from the key switch. My meter reads a ground with key in and door open. Clears when door shuts or key removed. It works perfectly. In search of the buzzer that plugs into this connector.

Only schematic I can find it 70-71 and does show it in the horn relay. Can't find schematic on 72. I bought the car from original owner in 1984 so am confident this is how the factory wired 72's

Same suggestion... a photo would help others understand what you are describing.

What wire colors enter this connector? Is nothing plugged into it? ???

Yes, it seems the pink wire did not copy but was there...

Seems a mismatch between the observations and both schematics. Could be:

- there's another terminal on the horn relay without a wire connected
- both schematics are wrong and there is indeed a separate buzzer on a 72

Definitely a confusing situation.

Does anyone else with a 72 have a horn relay under the dash and not on the firewall?

I added the missing pink wire (note that it is labeled) to johnta1's schematic.
