Fits 2005 Yamaha FJR1300
Fits and works. I don't think that was my issue anyways. Still had a short on the horn after install. So now I have spares. No complaints here.

Standard 4 pin 12v relay, no problems
Nothing fancy. Relays do not have the 5th NC connection, which often isn't used anyway. They give a 30A rating for it, but it isn't there. Plastic mounting tab, so mount it somewhere safe (or use it in a box and cut the tab off). No problems so far.

Wayyy cheaper than an autopart store
Works like a charm. Way cheaper than an autopart store. O'Reillys wants $20.00 just for one of these bad boys, not happening.

Perfect match
Used for after market lights for Polaris ATV. Probably will not need the second one, happy to carry a spare.
