I'm trying to figure out where my horn wires are. the PO must not have been able to fix it at one point and just wired in an aftermarket button on the bottom of the dash. is this the horn switch in the turn signal switch? I'm thinking about cutting the factory pigtail to the horn switch, and running new wires to the switch, then through a relay for the horn so I can get it working from the steering wheel again. anyone know which wires I should be looking for?
