Desperately Need Help Getting Fog Lights Working Again

[M4One]

I've got aftermarket foglights, purchased from Jimcat on this forum, installed on my '07 hatchback. They were working, but then a couple of months ago just stopped. Figured it was the bulbs, bought new cheapos from ebay, put them in and still not working. Checked the fuses in both the relay and underneath the dash. Neither looked as if they broke, but replaced them anyways.

My foglights are installed via this method:

Because the red wire on the kit I got did not have the proper connector, I had to go out and buy a seperate Yaris wire harness, take one of the wires and splice it together using a butt connector. I've had to try and reconnect the wires because they came loose. I think I'm connecting the wires properly. The light on the foglight switch turns on so I'm wondering where the problem is? Would I be better off trying to connect the wires together using a wire tap? I also have a Denso relay, but it's not plugged in. Would that change anything?
