These pictures have been made posssible by RDC from the
www.xbox-scene.com forums and are being posted with his permission. He posted them for people to use in case they need help troubleshooting their wireless controllers. These are very helpful if you have messed up a soldering point or trace and will come in handy to find easier points to access the required connections for the rapid fire gear or any other controller mod.
Note: The Matrix version is a Controller PCB v1, and the CG is a Controller PCB v2. Be sure to use the correct set for troubleshooting.
Quick Tip: An easy way to tell if your controller PCB is v1 or v2 is by the crosshatch on the top of the PCB. If the crosshatch is verticle and horizontal (like a checkerboard or tic-tac-toe grid) then its a v1. If the crosshatch goes diagonal or looks like a chainlink fence, then its a v2.
