Hey so I'm having trouble wiring up my horn.

I recently purchased a 1991 non turbo, and it didnt have a horn hooked up, but it does have one working horn (it works when I give it +12v from the batt).

When I push the horn button on the wheel, I can hear the relay clicking in the cpu by my feet.


Apparently a green/red striped wire should run from the cpu all the way to the front of the car? I can't find this anywhere in my engine bay. There are two blue wires that appear to hook up to the horn just fine, but I cant tell where those blue wires go.

Any help is greatly appreciated.
