I was trying to find out how the previous owner wired a horn relay and try to get the horn to work. I started the truck and the engine went to 2000 rpm, no throttle control with the pedal, and would not shut off when I removed the key. I had to disconnect the edge module to stop the engine. The only thing I did was touch a wire (from the aux relay that was spliced into a cable with a yellow and blk/wht wire) to the pos terminal and heard a noise from the relay. My manual from Geno's has faded ink for the relay diagram so I can't tell which is the original horn relay to try and switch it with the added relay.
