OK brace yourself I took a few pics
This first one shows where I spliced into the wiring harness. It's an orange wire, heavy gauge, off the large connector bundle right near the fuse box.
This next one shows the in-line fuse holder, one pig-tail of which is what I spliced into the harness with.
This is a shot of the relay itself. Mine came with the horns... So I dunno what you would do about buying one off the shelf. Once I understood WHAT the relay did, the wiring was simple. You can see the hot wire coming from the harness, and the old horn terminals plugged in too. The other hot lead of the relay went to one horn, then I spliced into THAT to feed the second horn. Then ran a wire from the first horn back to ground on the battery, again splicing into it for the second horn.
Clear as mudd?
