Horn relay

[Jim in S.C.]

Can someone post a wireing diagram or tell me how to wire a snyder's horn relay part number a-13820 ? I have one and don't want to blow it. It has a yellow wire,a blue wire and a red wire.
Thanks

Mitch, Thanks for taking the time to post the instructions. It was a used relay and I had no instruction paper. I put it on and the horn sounds great.
Thanks
