Why did I blow a fuse on my new aftermarket fogs

[hotdimmes]

So I'm fairly convinced I blew a fuse on my new fogs. It's set up so there is a wire on the + side of the battery, goes to a fuse, goes to a relay, then splits off to the fogs and the switch which consists of power from the relay, signal from the thick green wire underneath the steering column, and a ground. Everything was working initially for at least a day.

Could I have blown a fuse from having the switch set to "on" while I tried to start the car? Too much current or something?

I just don't really know what to adjust to make sure it doesn't happen again. I wired them the way I did so that I could operate them independently of the headlights, yet make sure they turn off if i turn the car off.

Note to self, the "blue" taps are not big enough to tap that big green switched ignition wire.
