Plug & Play wiring kit to intercept the High-Level speaker signal from the factory head unit to send to the Kicker KEY200.4 amp, then back to the speakers through the factory wiring.

Please note that this harness does not include a turn on signal.  The auto-on feature of the amp must be used.

Fully Plug & Play Kits

Select your vehicle model and year for a fully plug & play kit that plugs directly into the factory vehicle wiring and your KEY200.4 amp. Currently compatibility list (harnesses for other models are not available):

  • 2021-2023 Ford Bronco (Base Audio System)
  • 2022-2023 Ford Maverick (Base Audio System)




Installation Location

All harnesses are approximately 4' long, which allows installation of the unit under the dash on either the driver or the passenger side.


Install Kit Option

The amp must be powered directly from the battery or a portion of the power distribution system.  The current draw is too high to power off an existing circuit in the vehicle.

Don't Include Install Kit

The base harness comes with (2) 12" pigtails for the power and ground wires (12ga TXL) to the KEY200.4.  Choose this option when you have your own power and ground wiring and all fuses and terminals needed for the installation.

Include Install Kit

The install kit option gives you everything you'll need with a pre-installed waterproof fuse and ring terminals for attachment to the battery and chassis.  This option includes a power wire sized to reach the battery, and 3' ground wire (12ga TXL) in nylon-braided sleeving.  No extra work is required beyond routing the wires and attaching them to the battery and chassis.
