Inside a K range actuator

The FF CP is suitable for fitting into K-Range actuators; wiring diagrams similar to 1612ZFD detail the
option card connections. The FF CP module is fitted in the only option board slot inside the K-Range
electrical housing.
SK2 on the FF CP card plugs directly onto SK9 on the Main card, while a terminal bung loom brings
the FF highway signals to SK3.

Fig 3.5: The FF card located in a K-Range actuator
The FF card should be replaced or fitted only in a suitable environment. The actuator must be made
electrically safe before opening any covers. The electrical housing cover should be removed after
unscrewing the four 8mm Allen machine screws.
The FF card is attached to the main card by three plastic pillars, with one metal pillar, Torx 20 screw
and a fibre washer; as shown in the illustration above.
If an actuator is having the FF fitted for the first time, then the terminal bung loom must also be fitted.
The terminal numbers will be found in the appropriate wiring diagram, which should be included in the
fitting kit.
