The cut red wire in my photos is a wire that is clearly a stock wire that is in the Y harness behind the dash - the stock harness above the steering column and feeds the components behind the dash.
I have an after market steering wheel where the previous owner did not hook up the horn so that I dont know about the connection or the relay location.
I did find by the schematic that the dark green wire at the steering column is for the horn. I know it was months ago when I was able to sound the horn by applying a ground (I believe I grounded it anyway it was a while ago). to that dark green wire at the steering column. I was able to get the horn to sound so I assume the wire inside the column is not right. I was going to tackle that another time. Larger fishes to fry right now.
I think the horn circuit is wired correctly but am not sure at this point. Once I figure out what this red wire is for I will find the horn relay and see if that circuit is wired right.
Months ago, I did find two red wires outside the firewall behind the fusebox that were really shadily spliced for whatever reason - I think to bring power into the cabin but not sure. I cut out those butt splices and correctly spliced the cut wires and sealed from weather.
I am not sure why people mutilate these cars for wiring purposes when you can just bring another circuit to wherever you need it easier than cutting existing wires.
