VSC Off, ATRAC On Mod complete!
I completed the VSC-off mod on my T4R. The cool thing about this mod is the ATRAC is still active.
A great thank-you to Andries at T120. This is his hard work not mine. What it's like after the mod is complete: In 2wd dash lights are on (VSC & Diff lock). I didn't mess around enough to decide if VSC is working, traction control IS working; I'm assuming it has full VSC. It has all the familiar noises and accompanying reduction in power.  The system seems to get confused if you attempt to change from 2HI to 4HI with the switch on. Lights get stuck in flash mode.In 4HI it works as advertised  You have an unlocked Torsen center diff and no interference from the VSC; the VSC and Diff Lock light are on. You can definitely feel/hear ATRAC doing it's thing. The same deal in 4LO... I can lock and unlock the diff while in 4HI (or 4LO) with my switch on. It locks & unlocks ok. When unlocked the diff lock light continues to flash even after the diff unlocks. It is not a perfect mod. It beats the heck out what Toyota gave from the factory. I am thrilled! My advice is to not do a mode change with the added VSC switch on (grounding the wire). I may retract/amend that as I learn more. For now I plan to lock and unlock the diff, switch 4HI to 4LO with my added VSC switch in the off (ungrounded or open) position. The bottom line is it's a great mod that facilitates the use of 4HI and 4LO without VSC interference and the center diff unlocked. Andries saved me thousands! I was having serious 'VSC-off' envy of the 2008 guys!  This is the original Andries, aka Bulldog, thread: http://www.toyota120.com/forum/showthread.php?t=3817 For further discussion of what the mod will do and why you may or may not want it read here:http://www.toyota-4runner.org/showth...595#post361595 Below are some how-to pics Battery should be disconnected for this procedure! There's a TSB that discusses the risks; basically disconnect the battery. Do not turn or change 4wd mode knob until it's all back together and powered up.

The rest of the pics
  You can't see it but I put a couple of connectors on the switch wires also so that I can take the dash apart later without pulling and/or cutting wires.

So wait a second---will this work on a 2004? I heard there were some issues with resetting the lights or something like that.

 EDIT: I have had no reset issues thusfar. I have it in for a while now. There's no need to shut the vehicle off or anything other change the switch position.

So even if the VSC is deactivated by your switch it shows the center diff is locked when it is not . like in the picture ???
I have a V8 so how would that differ from the v6 as far as what lights up and when. Why didn't you get a factory VSC off switch from an 08.

2) The procedure was developed for a V8 and the lights work better. The V6 has AAD (ADD?) on the front axle and that requires a couple of extra wires. That's what I need to on Fri or Sat. 3) I might. The factory switch is a momentary and will require the use of a relay (which is fine, in fact better). As wired now I have to shut the switch off when I shut the truck off otherwise on startup the VSC/ATRAC computer can't complete it's self check. By using a momentary switch/relay combo it will return to 'normal' every time you shutdown (like the side airbag defeat button).

I must be misunderstanding . I thought and it looks like the diff lock light is on in the picture.

You're correct, the diff lock light and the condition DO NOT agree... The light is on but the diff is NOT locked. The whole deal is to trick the VSC into thinking the center diff IS locked thereby convincing the VSC to take a nap. When I work on it this weekend I'll let you know if the light indications improve/change.

Well thank-you and I get called many things, genius isn't usually one of them. Truth is it's not me... From the 1st entry in this thread, "A great thank-you to Andries at T120. This is his hard work not mine."
