Not I said the fly.

I'd like to get back to this. Can anyone identify which ground wire goes to the ABS pump? I think the best solution is a ground interrupt to a rocker.

Are you having any issues with your setup that tricks the truck into thinking the fuse is pulled?

I stopped using it after I posted it on this thread. It's janky. Anything that takes the place of the fuse isn't going to last.

^^^ said jankyness being reason for curiosity about ground interrupt.

Can someone take a picture of the pump and ground?

Where abouts is it?

I would love to get this going. Winter is coming!

The ABS pump is next to the master cylinder.

Ah yes. I tried to snap a pic of it long ago for RetiredBLMrig, but there is a piece of plastic covering it that I could not figure out how to get it off.

The only wires I see coming off the pump go directly into a large wire harness next to it, with a section shooting off nearby that goes to the ground on the frame. Its pretty obvious one of the ground wires in the drivers side front wheelwell is from the ABS pump, I am just not sure if it may ground other things as well because it comes from a large wire harness.

So has anyone tried disconnecting them? If not I will try this weekend

Did you ever happen to try this?

I'm going to try to get into it this weekend.

I removed the abs pump fuse. Never been happier. Won't be putting it back in.

I like the ABS, I just want to shut it off when I choose.

Exactly! The traction control stuff isnt all that bad either for daily driving... performs very well most of the time.

Pulling the fuse works phenomenal for off roading. No ABS, no traction control nannies...I would just love a simple switch instead of having to pop the hood each time. For off road excursions its not that big of a deal to me to pop the hood and pull the fuse... its the times when I just quickly want to slide the truck sideways for a second and I freakin' cant.

Keep us updated Reloader!

I snapped these pictures before I left work today. The newest schematic diagram I could find was for a 2015. It looks like the ABS ground wires are connection #G802A and it looks like it is located somewhere on the drivers side frame rail below the ABS unit or battery or fuse box.

Gee, I wonder what would happen if a guy interupted those ground wires? I wonder if a guy would have to push the start button twice to start the truck? I wonder if anything else shares that ground connection? I wonder if the ABS light would turn off by itself after it was reconnected?
Golly, if I only had a 15 or newer truck with a warranty, maybe I could figure it out.

The ground cluster you see inside the wheel well on the DS is the ABS ground as well as the main harness ground. Looking at the wires, the ABS ground wires are the small pair bolted behind the larger cluster. The two ABS grounds are attached together in the eyelet. If you remove them from the ground stud the truck will not start. Both wires are black so I'm not sure which does what. Further, when you try to start the truck it throws a CEL. The CEL's are stored but can be accessed with a simple OBD2 reader (and cleared).

I don't know much about the system so I am not sure if you can disrupt the ground and still have a functional vehicle. From all of the trial and error I have done I am certain if you splice the power wire going into the fuse block and then routing through the open state side of a relay you can make a functional ABS disconnect. If you could determine which ABS ground to clip that would be by far the easiest to wire. I can't find a stealth disconnect via any route thus far except pulling the fuse.

How are wires connected into the back of the fuse block? Is there a way to remove wires from the fuse block?

There are three plastic plugs, two above the spring bucket (outside) and one on the opposite side in the engine bay. They have goofy cross tip screws in them. I had to remove the King reservoir mounts to get to them.

I will clarify. 80% of my driving is on gravel. And half of that is in winter with snow and ice. Abs has tried to kill me for years in every vehicle I've owned that had it. Many of those vehicles either ended up hitting deer or moose or taking the ditch because instead of locking up on gravel the "smart" abs tried to keep the wheels rolling. Trying to stop on marbles basically you need to dig. So for my situation I couldn't be happier without abs. I had it pulled from many of the other trucks for years or in some vehicles it would fail and you lived with the abs light. And you can keep your nannys. I Borrowed newer truck last winter and it couldn't get up a moderate icy and snowy driveway without 4wd low because it kept pulling the power. Throttle pedal meant nothing. Don't worry your tucks will soon stop for you too. Won't need either a gas pedal or brake pedal

No shit, what do you think we discussing? The ABS works well for about 90% of pavement driving, the other 10% it's trying to stop the truck. Offroad the ABS isn't needed at all. All modern ABS/TCS systems do this. A switch to turn it off on the fly is the objective.

Haha I know. I just hate those nannies so much.

Well I gave Santa my list, with the nannie kill-switch right at the tippy top of it. Hopefully he can deliver.

I have been driving around for the last week with the fuse pulled. It is so nice, but I would still prefer to have it in on the main roads.

something like that?
the pump is part of the hydraulic control unit (hcu).
take away the abs module ground (g802a).

That looks very much like this to me

Pulled the 40amp fuse today and had so much fun without the truck interfering offroad I don't think i'm going to put it back. The tire pressure hazard doesn't bother me (don't have tire pressure sensors), no bother with two more lights (ABS and traction control off) on either. The only time it is nice is in the snow/ice on roads. Any other time I just don't need it. A switch would be the best solution bot for now it stays out.

BINGO!!!!!!

Although I still put my fuse back in most of the time, as I DD my truck MUCH more than anything else, and I want the systems in place for that. Hence the need for a switch!
