DESCRIPTION

Fits: 2010+ 4Runner 

What It Does

  • Gives you manual control over your KDSS system.

  • Lets you open and close the KDSS hydraulic valves electronically.

  • Helps correct or reduce the common “KDSS lean” after a lift.

  • Plug-and-play connection at the KDSS ECU — minimal wiring required.

  • Works with a dash switch or your existing switch controller (Switch-Pro, etc.).

Why You Need It

  • From the factory, KDSS automatically locks above 12 mph for on-road handling and unlocks below 12 mph for off-road flex.

  • That’s great in theory — but in reality, it’s overly stiff at the wrong times and unpredictable after a lift.

  • With this harness, you take control.

    • Flip the switch to unlock the system and let the suspension move freely.

    • Hit the switch again to lock it back up for tighter cornering.

    • Use it to balance the system, cure KDSS lean, and dial in the feel of your suspension on your terms.

How It Works

  • Uses genuine OEM Toyota connectors, pins, and color-matched wiring for perfect fit and reliability.
    Connects directly to the KDSS ECU — no cutting or splicing factory wires.

  • 3D printed resin connector housing (since Toyota never made a true mating connector).

  • Harness is QC-tested before shipping.

  • Simple crimping required to connect to your chosen switch.

Install Notes

  • Harness only — does not include switch or fuse box cover.

  • Add the DRKDSS KDSS Harness Combo for a full plug-and-play setup.

  • Use your own wire extensions, connectors, and mounting hardware if running custom switch locations.

  • Does not remove KDSS malfunction codes if the system is already faulted.

  • 2020+ vehicles will get a kdss malfunction error on the screen, all you need to do is hit ok and be on your way


Model Year & Prado Compatibility

⚠️ Prado owners — you must check your connector pin layout before ordering!
 Look at the wire next to the connector clip:

If the slot next to the clip is empty → Order 2010–2019 version (Picture A)
If a wire is in that slot → Order 2020+ version (Picture B)
 Right-hand drive Prados may differ — contact us with a photo before ordering.
