Thanks Bill. It does - it's built into the new fuse box. I'll have to review the wiring diagrams. Thanks for the inspiration. If you are planning to use the original 2 terminal horn you will need to change the wiring at the horn. One of the wires (I don't think it will make a difference which one - maybe some other Bolter will have more expertise) will need to be connected to ground, the other to the horn relay. Before you start wiring changes, use your 12v battery and some spare wire to test how your original 6 volt horn reacts to 12 volts. You may decide that you want to change horns.
