I am sorting out the electrical issues on my 74 'Cuda and am now on the topic of horns. They are missing from my car. I cleaned up the front light harness and found a single wire, green/red stripe with a single female spade connector. According to the wiring diagram this is the horn wire. It is my understanding from the diagram that there are two horns. I assume the single wire attaches to horn one and there would be a jumper wire that connects horn one to horn two? If anyone could provide pictures of wiring and how/where they attach to the car would be greatly appreciated. Also, is the horn relay plugged into the fuse box inside the car? I have what appears to be a relay mounted on the driver's side inner fender that is beside the ignition relay. The best I can tell, this is something for the seat belts....maybe?
On my 1970 Barracuda, my wiring harness has two spade connectors. The wire enters spade #1, and another dark-green/red wire leaves spade #1, and connects to spade #2 with about 12-inches of lead between them.
It's unclear if this differed in 1974. If it isn't supposed to be different, you seem to be missing the second part of the harness. Closely examine the wire side of that spade connector. Maybe you can see evidence of the missing 2nd wire.

My build sheet lists only one horn for my 73 Cuda.
I think they are all like this, the J31 code refers to both horns... a horn assembly, if you will, hi and low, part numbers #2808868(Low) #2808869(High)
Note even the 1974 parts book lists both part #s for the horns on an e-body. refer to section 8-32-2.
UNCOFIRMED: But as others have said, in later years, this code referred to only a single horn. I presume its the lower.
Interesting. My 74 broadcast sheet has nothing listed in the Miscellaneous J3 slot.
