Figure 7 Disconnecting the Flex

a.Use the flex connector opening tool, large curved end (Motorola part no. 6680334E08), or like instrument to help raise the sliding portion of the connector approximately 1/8 of an inch from its seated position. A slight prying action will achieve the best results for unlocking the connector.

b.Remove the flex from the chassis connector.

7.Remove the contoured O-ring/antenna bushing seal from the chassis.

8.Disconnect the controls flex from the connector on the controller board by following the procedure in step 6a and 6b.
