How many of you hate the ABS system in snow or while offroading on soft/loose terrain? I've had the ABS kick in so many times and almost make things worse on snow and gravel that I almost wish I didn't have it... Or at least had a way to turn it off...
Thanks to a redneck working electrical magic with the USAF in Germany we have a solution! Thanks to Tacogrande on TN again!

This will only cost a you a new switch, enough wire to run from the ABS ECU to your switch, some zip ties, and some time.
To Clarify some points here: Do NOT cut
the wire! Splice
into it for the ground! I used the ABS ECU (Passenger side, under hood) wire after talking to Tacogrande to clarify somethings (instead of the 4wd ECU wire I originally posted). I had cut the wires. Once they were reconnected, then grounded it worked.
Here is the wire: (I cut it by mistake instead of using a quick splice, so ignore the shrink tape. It's around the blue w/yellow striped wire.)
I sent the red wire for grounding it (thinner one, thicker one is for my 12v bed outlet) over to the driver side and through the grommet below. I zip tied it along the firewall to keep from touching the engine or exhaust.
I used a blank switch next to the steering wheel and had to trim the hole slightly for my switch to fit. I used a switch with a cover to prevent accidentally turning the ABS off.
The blank was cut down with a dremel so that it was just a face plate to keep the switch from pushing too far into the dash. The hole is tight enough to firmly hold the switch. Just used a pocket knife to trim a little plastic until the switch would push in (took a bit of effort, but you want a tight fit).
Note: This makes it THINK the locker is on so the locker and ABS lights are on. I tested it and it works. I don't have VSC (Vehicle Stability Control) or TRAC (Traction Control), but I'm told they are also turned off. Makes sense since all those get turned off when the locker is on, and this makes the truck think the locker is on (without triggering the actuator).

This has been more or less completely rewritten since I did it, got confused myself, had to clarify a few things with Tacogrande, and test to verify it works.
aka ABS kill switch (for added search key words)
You can also splice in at the 4WD ECU on Pin 20. This might help people with different colored wires.
