Mad Catz made some minor changes to the ground planes in the TE2+ upgrade that they did not let us know about.  Because of this a simple transposition of the wires on the end of the cable that plugs into the TE2+ board must be done.  The configuration of the TE2 and TE2+ are shown here:

By gently pulling the black tap back on the header, the wire may be pulled out of it's respective slot and moved.  Take care not to bend the tab too far so it can't retain the new wire that you will insert.  A paperclip or fine tweezers can be used to do this.
