Frequently Asked Questions

Does the DK4420 include the rocker switch?

Yes. Dometic's SeaStar jack plate literature identifies the basic rocker switch as included with the jack plate harness.

Is DK4420 the same as the DK4220 SmartStick kit?

No. DK4420 is the jack plate wire harness. DK4220 is a SmartStick position sensor and gauge kit used to provide jack plate height information.

Will DK4420 fit every SeaStar jack plate?

No. It is intended for compatible SeaStar Standard and Xtreme hydraulic jack plates. Manual jack plates and some older Detwiler or D3000-series systems use different electrical components. Confirm your jack plate model or existing harness part number before ordering.

Does this kit include the actuator or hydraulic jack plate?

No. The actuator and complete jack plate assembly are sold separately. This listing is for the DK4420 electrical harness kit and basic rocker switch.

Can a bad harness cause intermittent jack plate operation?

Yes, damaged wiring, loose connectors, corrosion or a poor power or ground connection can cause intermittent operation. The switch, circuit protection, battery connections and actuator should also be inspected before replacing parts.

Is professional installation recommended?

Marine electrical installation experience is recommended. Disconnect battery power before service, route the harness away from heat and moving parts, protect it from chafing, and follow the applicable Dometic installation instructions.
