does anyone have a diagram for the horm wires on a 67 firebird? it isn't in my Chiltons book. thanks

I dont know if this is what your asking for but here is the front end wiring diagram:

Here is the back end:

I have it committed to memory. The wire from the horn switch goes down the column and then out to the horn sending unit. It provides a ground to the relay in the sending unit. When the unit gets a ground it provides power to the wire that goes out to the horns. I believe the sending wire is blue and the power horn wire is black. I see now, after looking at the schemo, that both wires are black. One of us is wrong!
