How many horns on a 79 C10 Custom Deluxe

[CWells]

I recently installed a new light circuit harness under the hood on my 79 C10 Custom Deluxe and it has connections for two horns. However, I have only one horn. Can anyone tell me if two horns were standard on all 79's or did some have only one horn? thanks Curtis Wells

I'm going to go out on a limb and say that the Custom Deluxe came standard with a single horn in '79. I will have to look to confirm, but I'm almost positive that my Scottsdale trim '79 has "Dual Note Horn" listed somewhere on the sticker or data tag inside the glovebox.

My 78 custom deluxe only came with one horn, but had the connector for a second one. I added one as I went along.

I wanna say the harness should have both plugs, but the basic truck only has one horn. An extra one is an easy add if you have the grille out though. Cadillac's had multiple horns and they're deeper notes, so that's an option too. Dad had em on the '79 and '84, sounded good.
