This is where all the fun is. Following the wiring diagram, wire everything up. If you decide to use heat shrink to protect the connections from touching be sure to cut to length(usually 1/2" pieces will do) and slide them on the wires before soldering. Then slide up over connection and heat it up. It is very important before wiring to make sure you have enough wire to reach everything. It is better to have too much than too little, you can always tuck away an inch or two of extra wire.
