Well i set out to be able to shut off the traction control completely from inside the cab (Not pulling fuse) and allow locking of the rear Diff at any speed for off road use.
I started but installing a Raptor Center console for the switches and used the location of the hill decent control button to install my push start systems button (didn't want to relocate the 4WD switch to the passenger side as the kit calls for.
started by installing the console, Push start button and wiring up the AUX Switches:

then i decided to tackle making the off road button functional for my TC disable and ELD lock. Since the button is a momentary switch (doesn't hold current when released) i didn't want to have to hold the button down to activate my mod. I used a Altronix RBR1224 watching relay:

this relay takes a momentary signal and allows it to flip between 2 Circuits.
wired up the Off road button using WPT-923 (PN: 8U2Z-14S411-XA)
which wires up as follows:

ran wires to the relay like this:

Now when i press the Off road Mode button it activates the relay open the circuit to the ABS and Closes the circuit to the ELD; and activates the LED on the Off road button.
Traction Controle is completely disabled and the ELD stays locked at any speed. then when i press the button again it reverts back to normal unlocking the diff, and enabling the Traction Control system. Also when the Button if off every thing functions as normal know pull still locks Diff under 25, Traction Control button cycles thru the Advance track features

and yes i know this mod could have been easily achieved using one of the AUX Switches and a 5 Post SPDT relay. i only needed to figure out the watching relay due to the raptor off road modes momentary activation. I used a AUX switch and a 5 post SPDT relay on my previous 15 F-250, but i had the off road button and wanted to make it function for this purpose and heck i had a 6 pack and wanted a project.

awesome work. Gives us another option to look at if we want to do these mods.

No problem if any one wants any more info or diff pictures let me know it was surprisingly simple most complicated part was figuring out the button and ratchet relay. tested it about 4-5 times on the road and worked perfectly and then found some dirt and tested it there works great. it does thro service advance track and service Locking diff warnings when activated. this can be eliminated by adding diodes but my thinking is if i add diodes ill lose notification when it engages. i like seeing confirmation its working.
all warnings go right away once u turn off the button

Do the warnings affect anything else? I know one of the offroad shops, SDHQ I think, makes the eld locker module and I know many people have found other ways of locking the diff.

ASars

Nope no other issues just warning lights u can clear with the ok button on the steering wheel. Then they all go away when u turn it back off.

So what actually disables the traction control, the off road mode input to the TCCM? Do all trucks have the off road mode input to the TCCM?

ASars

there no connection from the button to the TCCM i listed it step by step.
removal of the trascion control fuse and wiring it to the ratchet relay when the relay if off the circuit is closed and power to the trascion control system, when the relay is activated it opens the circuit and stops the Trascion control circuit form getting power
