In a US spec W126 500SEL, where are the main horns and where is the highway horn? I'm buying the main horns from someone parting out a car. I'd like a matched pair of main horns. I don't need the highway horn. I'd like to describe in words which horns to send. If someone has a picture to share that would be awesome.

Thanks,
Sixto
