Hi There!

I'm having trouble identifying the Horn Relay. I believe its the one on the far left, but it looks different than relays in other cards. I know I've seen you can often times swap the horn relay with the rear defroster relay in order to run a quick test by switching them both and see if that works, but I'm finding it a lot harder to tell.
If I posed an image, would you be able to help further? Really appreciate your wisdom!

To note, fuses look good for horn.

Thanks again!
Tallulah
