Almost there, just one more wire! (Well, really 2!)
The kit comes with a little junction box (30 amp circuit breaker) with a rubber cap on it. Remove the rubber cap. Take the nuts off and put the thick red wire from the power relay on one side of the 30Amp circuit breaker, put the nut on and tighten it down. There is another "loose" thick red wire that comes with the kit. Put one end of it on the other end of the 10 Amp circuit breaker, put the nut on and tighten it down.
Next, install the circuit breaker somewhere. I installed mine in an existing slot looking thing on my fender. I drilled 2 holes and installed screws with nuts to hold it down. Put the rubber cap back on the circuit breaker.
Next, you want to take the nut off of your batterys junction box and put the last loose end from the 10 Amp circuit breaker on it and tighten the nut back down.
Make sure the battery is still unhooked 
YOU NOW HAVE THE WIRING COMPLETE!!!! WOHOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
THAT WASN'T SO HARD NOW, WAS IT?
