The SCU is located behind the dash panel on the driver's side, to the right of the steering column above and behind some white plastic duct. Look at the picture in my original post for reference.
Disable KDSS with toggle switch?

Hi Akkording,
I think if I wanted to perform an experiment of "Temporary KDSS disengagement"; there aren't a lot of wires the in convenient locations e.g., in the dash...etc, I might install a 'single pole/double through' (spdt) relay on the GND wire (White w/Blk stripe "Stabilized ECU".
The reason for the SPDT relay, is because I don't know if the ecu normally operates when Energized or De-energized, so it can easily be switched around just by swapping one wire on the Normally Open, to the Normally closed terminals (or vice-versa)! I looked at a wiring diagram of that system but there are three ECU's that are networking together...
Main body ECU, Stabilizer ECU, and the Skid control ECU; which are using the four wheel speed sensors to control how KDSS is supposed to work! And like [MENTION=150567]Old Red[/MENTION] has stated, you don't want the truck to start throwing DTCs in the CAN-bus system! The "Stabilizer ECU" has a Blk feed wire coming from the KDSS 10A fuse in the D/S fusebox!
This power source is HOT when in the on or start position. I might break the GND (Wh w/Blk stripe) wire, since our trucks utilize a Ground-side switch mode! And even then you may start throwing DTC's because the Stabilizer ECU has lost power; that's why I refered to this as an experiment! Hope this helps, 'Best to you'

I could definitely benefit from an on/off switch. But I'll let more technical folk figure this one out before I start hacking up harnesses.
I like the kdss alot but I want to control it. Just like switching throttle maps on the pedal commander for street vs off road conditions (Sport + vs Eco), I want to just switch the KDSS off (open) when I hit dirt.
It would be like having two different trucks. One is a "corner hugging" responsive daily the other is a plush and capable off roader.

Yea they were dealing with the harness on the outside of the vehicle where the open/close valves are i think.....driver side frame rail.

Im not really understanding how kdss has such an effect on the softness of the ride? Are you hitting bumps big enough to flex that hard while traveling faster than 12mph? I would think you would need to be flexed pretty hard for the swaybar to interfere with the shocks dampening. Just trying to get a mental picture here.

Sway bars stop your vehicle from leaning, typically in corners at speed, generally on a surface where traction is good, the body would tend to roll or sway the most. This benefit is, for the most part, valuable on-road. Certain types of off-road specific builds remove them completely. Others use, as mentioned earlier, disconnects.
Having no sway bar, disconnects, or an actuated sway bar removes some of the travel limitations of the suspension (ie makes it easier to travel through the stroke), giving you more tire to ground contact in offset terrain. It is easily possible to go faster in this circumstance and not be getting the full benefit of your suspension. 12mph is not that fast, particularly if you are accustomed to driving the terrain.

I understand the function of swaybars and how they affect articulation and lean, im just not seeing how they would stiffen up the ride unless you were really plowing through rough terrain at a good clip causing the suspension to eat up lots of travel...and in that situation I imagine the ride would be pretty bad no matter what unless you are running a plush LT setup...and if you are running a plush LT setup its pretty doubtful you have KDSS.
Not saying i think its wrong, just that it doesnt seem like sagging the swaybars would have a huge impact on the harshness of the ride.

In a similar way to how sway bars can transfer forces from side to side (and the KDSS sway bars are bigger), kdss also transfers forces front to rear which can make for a harsh ride at speed on bumpy surfaces. Turning it "off" puts an accumulator in series which dampens the transfer and makes it more comfortable. You dont have to be going that fast, just 30-45mph on a gravel road is harsh.
I need to make a switch. I have been testing this and for sure it soften the ride up as far as cross sections or anything that your suspension has to articulate. Like going through a drive way section at an angle etc.
Essentially what this does is make it like you are taking one away bar end link off. Definitely not like completely loosing the sway bar.

Let’s keep this thread alive.
That's easy- maybe one could not find a 4R like they wanted without KDSS.

I came across this harness from Blackgate custom and wondered if anyone has tried it out yet?

I don’t have time to search now but there is another thread where someone purchased the switch and was waiting to receive. They probably have it by now…
Edit…
Here is the thread, last post… from [MENTION=128285]sekurt[/MENTION]
Only KDSS w/lift need apply

Yep, that’s me that received the Blackgate switch. Nicely made harness and supplied AOB custom KDSS switch. I haven’t installed it yet since I am in process of acquiring a switchpros system. I originally was going to wire in the AOB switch but have now decided to go the switchpros route. As an aside, I received an email just today that blackgate is offering a 10% discount, code AMERICA10

The former partner at BGC also has a switch in the works. You can see his IG here: Login • Instagram
Seems the function is the same, yet the install is very different.

I just picked one up on the sale today and have a switchpro already so I should be able to install it somewhat quickly to test out

Thanks. I like this solution a lot more since it’s installed under the dash rather than under the truck… Price will be much cheaper as well…
I can't remember if there was a more recent thread, but I've been running with a kdss disable function for about 1 month now. Unfortunately I have yet to take it out on a trail due to some unrelated issues, but I do not notice a gigantic difference driving around town with it. It doesn't feel like it's going to just fall over sideways or anything like that, I 'think' I can feel a difference on some bumps here and there. This also may have to do with my some what heavily modified suspension already though.
Once things get settled for me I'll be back out on the trails every week or so. Until then, I have not ran into any issues with the switch, no weird errors or side effects.
