Kill-switch for electronic nannies

I'm starting off with a few questions so bare with me...

Does anybody know of a good source for diagrams of the wiring in our trucks? When searching on-line I have seen links to "the holy grail" of diagrams, but they are always broken links :doh:

Also, do the electronic nannies in these new PW's cause issues when using the truck off road in 2WD or 4HI (I'm assuming most of the nannies are shut off in 4LO)? If it is anything like my JK was it is a huge PITA, but I admit I havnt done much wheeling with my new truck yet (well, no snow or no 4HI yet at all).




With my JK one of my most favorite mods I did was installed a kill-switch for all of the stupid nannies. I find myself 2WD wheeling or 4HI wheeling from time to time, and that crap always kicking on drove me nuts. I simply installed a switch on one of the wires (violet with light blue tracer) going to the yaw sensor under the center council. When the switch was used it completely shut off all nannies; traction control stuff, antilock brakes, all that stuff. I am looking at doing something like this to my wagon, just a little sketched out about guess-cutting wires on a $60K truck just to see if it may work.

I took my center council/seat tray off last night and there appears to be one of those same type of yaw sensors there, just like the Jeep. I would just like to look a little further into exactly what sensor this is, and possibly what the wires are for that are coming and going from it.

Any input is greatly appreciated.

Funny cruz. If it didnt work it certainly wouldnt be hard to re-connect the wire I cut... I just worry about frying some type of sensor or something haha.

In my Nismo. I had to splice in a switch to the Yaw sensor to eliminate the nannies for doing trackdays. You had to do the samething on your jeep. Think you may be on to something with the PW.

Well I admit, I am not even sure if the PW's system is all that intrusive or annoying (where is snowsled :mrgreen: )... I just havent got to use the truck enough yet. But if it is anything like my Jeep was, then I want that shit shut off when I am off road.

I really liked all of the features when using the Jeep on the main roads. The worked very well. I never drove on the main roads with the nannies not in use. But, that junk isnt designed for off road use.

There is a yaw sensor under the center console. You can put a switch in that circuit. Another way to do it is to switch the circuit for the abs pump.

Easier way Olyeler is to pull the ABS fuse, which guarantees none of the electronic controls will activate & then you don't have to cut wires or install another switch. I'll run out & check this weekend and tell you which # it is.

Or wire a simple toggle switch to interrupt the ABS fuse. Dash will light up but you'll be nanny-free and can likely do it on the fly. Re-engaging normal operation would probably require restarting the truck, I'm guessing. Give it a shot and let us know?

I haven't experienced anything drastic enough to merit wiring a killswitch yet, the only issue I ran across was forgetting to hold the TCS button in 4HI before entering a large uphill sand wash that required a minimum speed of about 25 to stay on top... The ESC kept activating as I attempted to get out of the grooves and would slow me down to about 27, nearly getting me stuck several times. Anything under 20 and the ESC can be deactivated, for those who don't know. My mistake, won't happen again.

Or as Snowsled would tell the story: "MY POSER WAGON TRIED TO KILL ME." :roll:

Some of the tuners allow you to disable TCS.

In my Nismo. I have to turn the car off, flip the switch and restart for everything to go back to normal.

Yeah i guess if pulling a fuse worked i could do that too. The abs fuse will shut all that stuff off?

But really, cutting a single wire and putting a switch on it doesnt bother me at all, as long as it works.

In my jeep to get the system back on, the vehicle had to be shut off and then restarted.

The braking component of ESC runs off of the ABS pump, and without the ability to brake the whole system apparently shuts off. I believe I went looking for the fuse once, but the map printed inside the fuse block didn't match the table that was printed in my owner's manual and I didn't have time to go experimenting to find the right fuse.

Also, they usually put more than one thing on a fuse. So, if you disable it, something else may not work either. May throw a code/s. Most certainly it will void the warranty if dealer finds it, or the computer logs something was disabled & they see that.

The guys on this forum figured it out. http://dodgetrucksxtreme.com/index.php?topic=11468.0 I did read somewhere else the newer trucks were having issues using this technique. Apparently the dash was shutting off with the switch. I can't seem to find that link now.

Well I'll be go to heck. Thanks for the link, I will surely check it out!

Can you just clip the negative on the sensor and run wiring through a SPST switch?

No idea! Wth is a SPST switch :lol:

I am horrible with wiring.

Well get this. I now know that when the abs isnt working in a 13+ cummins truck, niether does the 4x4 :doh: wonder if that is the same for a pw.

Show me a picture. I have an SPST rocker and I'm willing to chop-fu for the good of the hive. My thought is a SPST switch that breaks the negative instead of running positive power. Run positive power to the rocker for cab lighting function and when the switch is activated. No actual power from the sensor though. Thoughts?

Here is a small writeup i did on Jk forum for my jeep. There are a few pics in there.

I would LOVE to do this to the pw.

Is that what the PW sensor looks like?

No not really. But there is lots of wires coming from it.

There is another sensor in there...if you unplug it your computer goes all unhappy.
