Rebuilding a burnt J6 GI connector: striped wires on the first four pins

If the J6 GI connector on the interconnect board has burnt so badly that the pin order is lost, the white-striped (return) wires go to the first four pins and the solid yellow wires to the last four. Replace the board header as well as the plug, since it will have taken the same heat.
