Install kit 500-6326-00, part 2: display controller end

Steps

• On the display controller behind the large display, unplug the old connector at J1. It is no longer used: tie it back and tape it, or cut off its IDC plug and tape and tie the loose ends.
• Route the new red and black wires from the CN6 plug down to the controller.
• Fit the kit's 5-pin IDC plug on J1 (keyed at pin 2): the doubled black ground wire lands on pin 3 and the doubled red +5 V wire on pin 1.
