We've had intermittent horn operation on our '67. That all came to an end a few weeks ago though when I disconnected the entire front wiring loom to chase down a "short" (you could also call it a faulty bulb!!!! AAARGH). Once I disconnected the horn I couldn't remember how it hooked back up, and since it doesn't work right all the time I can't just hook it up and test it.

In short: which wires go where on the horn relay itself? Thanks.

Looking down at the relay by leaning over the front bumper, the left screw post is used for the two wires with the spade connectors. On the right where the male connectors are, the single wire(black) goes behind(closest to you) the two wire(dark green) horn connector. Hope this is clear enough.

And Tom, I had the same intermittent horn problem when I got my '67 this year. Solution: clean all the contacts ( blades and spades) throuroghly and goop them with dielectric grease. Problem solved.

In fact I had my mini wirebrush, contact remover, sandpapaer and grease out all the time and I would touch up every contact I came across.

Thanks guys. I was wondering about the green and black wires that Rick referred to. I couldn't figure which went to which.
Another odd thing that made me leave it all alone was:
I got oil on the engine (don't ask) and had to degrease it. After I was done it wouldn't start, so I let it sit for a day and dry out. When I hooked everything up the next day the horn relay was producing a short! Since the horn wasn't working it would just make the solenoid kinda clunk, but power was draining from the batt. I just left it unhooked, figured that I had it connected wrong and that's why it was draining.
Gene, yeah it's rusty and crusty on those terminals REALLY badly. I gotta do maintenance there. We shall see if that fixes the short too. Hopefully, as I just got done with one and don't feel like messin' with a second so soon afterward.

Tom, that's how I found my prob. I thought I needed two new horns. I'd hear the CLICK and nothing, yet when I put the horn to hot it sounded off. Oh, one part of the terminal cleaning kit I didn;t mention is contact cleaner. I got some nasty trichlor based cancer stuff from the local steel plant and it works mint. The termnial tool is a litle ditty I got at Carquest. A $10 tool that lets you take those plastic ends off the spades to clean them right. Makes a world of difference, as will really clean connections throughout your ride.
