Yesterday I was playing around with my ground wires under the driver's dash. On my 87 fj60. A number of things went wrong. Long story short my horns are not working now. I have two hot wires on the horn plug. The one that is supposed to return ground signal to the steering wheel switch and ground is hot. When I remove the horn fuse the wire loses energy. Leading me to believe it is being energized by the same circuit, either the hazards hot wire or the horns hot wire. With the ground wire and hot disc from the horn I have hot on the ground/signal wire. I have hot at the other end of the wire (on the trucks harness side) when I disc it from the stalk harness.
With a 12v test light and a multimeter can I narrow this down even more without cutting the wire? Really don't want to take the whole dash apart to tear into the loom. Although if I can narrow it down to say the engine comp or the dash that would help. I did some looking at the drivers side wires under the headlight washer reservoir etc but nothing is burned up. If there is more voltage at one end would that be an indication of the ground fault being closer to that end? Strangely the other horn's ground is NOT energized even though the wiring diagram shows it splices into the other.
the pic shows the signal wire in question in red.
