I'm trying to figure out why my horn doesn't work.

I tested the two horns and one of them is dead, but the other horn works when supplied power directly from the battey, so I tried reading the electrical diagrams and testing stuff, but I want to make sure I'm doing it right.

The horn switch on the steering wheel has 12 volts, so I don't think its there.

I have power across fuse 16.

I have power up to the horn relay.

Here is where I get confused. I can't really tell which terminal is which as the relay has the pins labeled 1, 2, 3, 4, and 5, and I was kind of hoping to see 30, 85, 86, 87, and 87a like in the wiring diagram.

Regardless of that, my real question is this. Shouldn't I be able to jumper the relay from the hot to pin 87 and get the horn to work?

Thanks,
John

I assume the relay itself doesn't have a wiring diagram printed on it? (about 60% of the thousands of relays I've seen have a circuit diagram on one of the sides)
