Many people have completed this simple Mod and love it. It just takes some basic electronics skills and patience.

How to use seperate switch-
First, remove your key from the ignition, then remove glovebox and 10MM bolt on the latch
remove black plastic cover held in by latch bolt. You don't actually have to remove the ECU if you find connector F-12. It's the one on the upper right looking at the picture.
A DPDT on-none-on switch is basicly two switches built into one, so for simplification we will divide the switch into two "banks".
In the picture above you can see the divider between the two banks. On this particular switch the center poles are the commons, meaning current flows through them to either on end or the other. The difflock wires run from connector f-12 to the rear end, so the dangling wires will be the ones on the computer side, we hook the ones that run to the rear end to our switch. Attach M1, the green wire from pin 2 to one common, and M2 the Blue wire to the other common on the other bank. Flip the switch to the position you choose to be "UNLOCKED". Attach a 12V fused and keyed power source to the same bank as the blue wire, wich has continuity in the "unlocked position", and hook up the green wire with the black stripe (PIN 21) to the same bank as the green wire, wich has continuity in the unlocked position. Now flip the switch to the locked position, and hook up the pink wire to the same bank as the blue wire. Then attach another 12V wire to the last pin. Put your key back in the ignition, flip the switch to locked, wait for the lock light to stop blinking,and go lay some patches.

Pull your gauge cluster out and cut the violet wire with the white stripe. It's on the big connector on the left. Put a switch in if you ha... Show moreve VSC/TRAC otherwise it will throw a CEL when doing burnouts. Be safe, use this mod on a dyno or closed track with speed rated tires and all that.
So here's the plan, using a DPDT switch set one switch position for normal flow through operations, and use the other postion to trick the ECU into believing the front ADD actuator is engaged, without letting juice flow to the motor. All of these wires can be found on connector F-13, at the 4wd ECU behind the glovebox.
so for bank "A"
pin 1a RED WIRE, ECU Side (DM1)
pin 2a RED WIRE, Motor side
pin 3a OPEN
pin 4b LG-B(ADD) P-L(DL2), DIFF SIDE
pin 5b LG-B(ADD) P-L(DL2), ECU SIDE
pin 6b GROUND
4LO on the go mod
Ever notice you can't shift into 4LO with the truck moving? Simply cut the Violet wire with the White stripe on connector F-12 and it disables the speed control in the 4WD ECU allowing you to shift into 4LO while rolling. Just be careful not to lock into low while driving too fast or you might spill your coffee.You still have to push in the clutch on manual trannies, and put auto's in neutral to get it to shift.
Those of us that live with icy roads in the winter know ABS sucks in snow and ice. If you have ever tried to fishtail on a muddy road in 2HI you know VSC (vehicle stability control) sucks. And if you have ever tried to impress your friends with a nice smoky burn out you know TRAC or traction control sucks, so this mod shuts all that crap off for play time.
If you ground out the blue wire with the yellow stripe (pin 20 on the 4wd ECU) it disables ABS, VSC, and TRAC. I just ran the wire through a 2 pole switch to ground so I can still have the luxury of the soccer mom safety crap on the highway. Show Less
