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
