KDSS Control Harness Kit (Harness Only)

THIS IS THE HARDEST PART TO KEEP IN STOCK DO TO THE AVAILABILITY OF THE OEM CONNECTOR AS WELL AS THE PINS USED ARE LIMITED IN QUANTITY I CAN ORDER.  On top of that.   This is the only part that I actually manufacture all in house by myself and or family helps prepped them.  All other parts I used machine shops and fab shops to make parts and all I do I pick up and put on shelf ! 

Fits: 2010+ 4Runner / GX460 / Prado 150 with KDSS

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.

• Download the full KDSS Control Harness Install PDF for step-by-step guidance.

• 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
