and away from the terminal; make sure the ' dot ' or ' O ' aligns with the ' O ' on the terminal. The
flex must be fully pushed into the connector.
2. Check that the back housing O-ring seal is undamaged, and fits properly in the groove.
Replace the seal, if it is damaged (refer to the exploded view diagrams and parts list).

align with the snap catch grooves on the Enhanced Control Head. Press the back housing
until it snaps into place.

the chassis assembly. Replace the seal, if it is damaged.
CAUTION: Ensure that the dust cover is flushed with the diecast surface. If the dust cover is
NOT flushed properly, sealing failure may occur.
