I inherited a 2001 Toyota Echo with a horn that will not shut off when the relay is installed. I have decided to install an aftermarket dash horn. I need a schematic that tells me the colors of the wires going out of the horn relay. I could figure out how to wire the hot for the power and light, but am not sure which wire goes from the steering wheel circuit to the relay. I want to cut that line and hook it into the switch.
