Default Need to know where my horn/harness is located?

I ripped my horn clips out when I was changing my radiator and a/c condenser out. (Dont ask me how). I had some friends helping me and mixed with beer and the heat somehow I have no clue where the wires run for the horn are located and I can't find the clips.

I need to reconnect them, but I have no clue where to go or how to start. I've read a view diagrams and what not but still having a hard time.

I'm hoping to find someone that had their front end apart that could help me out to find the wiring and placement of the route of the wiring. I don't want to resort to popping up where the fuse goes and then having to custom mount something or make something.

Any help from anyone?

I removed my alarm horn because I have an aftermarket alarm.

I am looking for the hi and lo for the actual steering wheel horns. I need basically from the horn that mounts to the front of the vehicle to wherever the wiring will go (the route of the wiring and maybe some color visuals so I can be sure). Theres not much that was pulled off but I can't find the wiring and I dont want to just go pulling parts off.

Single back wire that runs to the relay box #2. Here are the 99 GS400 diagrams.

Do you have any pics of where it routes? sort of like coming from the wheel well and if its upper or lower in reference to the headlights. I know where the box is, I'm just not sure

Thank you as well. Appreciate it.

I have no photos of the wiring and the repair manuals do not cover routing. I am still curious to hear how much wire was removed and how. Its a single black wire from the horns so it should not be too hard to find if its still there hanging out.
