Relay mounted. Terminals will also get the soldering and heat shrink. I've got some really big heat shrink, so I'll likely cinch up the split loom that all comes together there.

One thing I've noticed is these cheap relays (not sure if yours is) don't fair well in the open elements (or the engine bay). I've had a few relay failures that were mounted in the engine bay. I'd look into a waterproof one or slather the bottom of the relay (along the seams) in grease to keep moisture out. Food for thought.
