Blown Lights Fuse

I need some help here guys, I took my bike apart and put on an undertail hugger. I tested all the lights and they worked fine. But then after I put the bike back together, it looked great, but somehow I managed to blow the fuse for my lights. I have turn signals and brake lights, but no tail light or head lights. I looked but can't find the fuse block. All i've seen is the battery, starter relay, and ecu. Can someone help me out?
