What are these wires - missing horn?

[Pablo M]

On passenger side (right) there are these wires just hanging behind my grille. Double brown and single with connector. Driver side has horn but not the same wiring. 
many suggestions what these are for?

On my 76er - the primary wrapped wires coming through that grommet feed the passenger side headlight/marker lights. Nothing on that side is horn (that’s all on driver side AFAIK).

The other thing coming through there is an ‘available’  fog/driving light tap.

 

My car also has AC - and I have extra wiring for that over there too. Your car ever had AC or driving lights?

The Green/yellow is for a right high-tone horn (400Hz).

Brown wires are the horn ground, shared with the left low-tone horn (335Hz).

Me too.

Does that make us extra horny?

[visionaut]

I’ve got two horns (2 long trumpets) on my 76er too - both wired & mounted on the drivers side. 
 

Learned something new: horns mounted on both sides.  (stereo honkers!)   thx John

You made me remember something. I looked through the box of random parts that came in the trunk of the car when I bought it 18 months ago. Found a horn. Back looks marked for the wire positions too. Wonder why they took it off and didn’t put it back on. When the car was repainted they didn’t remove the other side. Maybe they were going to replace it since it’s broken? We’ll never know. 
I should reinstall it.

If it were me I'd spend the 40 bucks and get a pair of Hella red horns, they are way louder at 120 dbs. than stock and with every other person on the phone or having the tunes cranked up it's needed now more than ever.

Loud is good.  Junkyard is also a good place to shop.  I copped my Stritones from the same 964 I got my seats…
