HORN: Factory Location for '72 - '80 Pickups?

Bought a '74 W200 Power Wagon last November, Restoring it.

I don't see a Horn anywhere under the hood. Guessing someone along the way removed it. When I get a replacement, was wondering, where did the Factory mount it?

Should be next to radiator shrowd someplace and possibly had green wire with a red tracer possibly?

I have a mostly unmolested 74 W100.

They are on the front side of the radiator support and mount to the top edge. Little hard to see here but they are where the yellow boxes are.

Thanks for the replies. Maybe mine is still there? For some reason, I didn't think to look ahead of the radiator crossmember.

Thanks Again.
