Let's get started. Items needed
9 volt battery, and a connector with or with out wire leads
about 4 inches or so, of wire.
Needle nose pliers
First I took the needle nose pliers and broke one of the AA battery sections off the battery compartment making room for the 9v battery.
Secondly I soldered the wires onto my 9v connector because mine didn't come with leads. next, I soldered the wires on the correct battery terminals in the controller. And then your done. Just hook up the battery, turn on the controller, if it powers up then, close up the battery compartment.
