OK, I found the horn it was in the control box and as I suspected it was disconnected. The purple wires where still connected and the tan wire was easy it plugged into the empty spade connector on the horn. But, the black wire with the round screw hole, it doesn't show on the wiring diagram. I grounded it to the control box and now the horn chirps when the key is turned on and with the key on and grounding the tan temp sensor wire the horn sounds continuously. I think I got it, but would like a second opinion. Thanks
