I bought my Scion tC ages ago, and it had this kit already in it:

However, today I was installing a bunch of LEDs and a short shifter (that was a pain) and I accidently broke a fuse that was right next to the shifter. I probably hit it with a screwdriver or something while I was trying to mess with the shifter. Anyway there is a yellow case thing, with a fuse in it, and I shattered the fuse. Anyone have any idea what kind of fuse I can use to replace it since now none of the LEDs under the dash or the cupholders will turn on.

 

I got a 2amp fuse and hope that will be okay

 

From what you described that's a #74 bulb with a yellow gel cap, replace it or switch it out with a LED, same bulb size for the cubby light in front of the shifter.

 

No, it's a fuse. I put a 2amp fuse in it and all the lights kicked back on. Not sure if it's the right amp/volt though. Hopefully I'm right
