I need a 12V source with a switch for a solenoid valve on a trailer. Are there spare spots in the stock fuse box on this machine? I do not have a cab. Any links to past threads for electrical modifications would be helpful.

I found two blank spots in the fuse box, one with constant power and one with power only when the tractor is on. The latter is perfect. How do I connect a wire into the back of the fuse box? Any particular connector needed? I can pick up a ground at the back of the tractor, so only one wire is needed.

I suggest you use the same attaching method as the other fuses. You'll probably have to pull the fuse box to do this.
I've never had my fuse box pulled, so I don't know what type connector is used. Might be a forked connector screwed tight to the fuse box...but that's a guess.

As far as running the hot wire...do protect it somehow. If you can bundle it with the wiring harness, great...if not, get some of that corrugated flexible plastic tubing. IIRC, it's $0.59 at NAPA. Use plenty of wire ties to secure it to the tractor.

As Roy suggested earlier,I would consider using a relay.
