5. Remove Trigger Motors
Gently remove the trigger rumble motors from the housing. On the previous step, it is likely
that these may have come out.
NOTICE: The motors are soldered to the main board. This solder connection is very
fragile at both the motor and board ends. Take care not to damage the soldered
connection
6. Remove Wires
De-route the wires that go from the trigger caps, over the mid-frame, and to the
mainboard. Once complete, set the rumble motors gently to the side of the controller to
avoid any damage or tension while they hang.
