If you have a TRD factory selectable locker it is an Electric locker, it is not air operated.
If so, you can do a gray wire mod to engage it without going into 4low.
Try to do a search for "Gray wire mod".

That's correct, if you are talking about the Toyota factory locker, it's electric. Not compressed air operated like ARB or Jeep Rubicon factory locker.

If you have a manual trans, do the "blue wire" mod, it's easier. If you have an automatic, you have to do the "gray wire" mod, or you'll have shift point issues.

Yes you can. With the grey wire mod you can engage the TRD e-locker in 4-lo, 4-hi, as well as 2wd. Great for donuts in snow. Also great for making your truck slide down hills when your stuck. When both those wheels get cranking, the tail seems to have a mind of its own.

I read the gray wire mod. out of Offroad.com, but my 2004 wireing harness didnt have the same color wires as his 2001.
Now there is a gray wire in the #8 slot as he noted, but i want to make sure this is the correct wire to ground..
thanks

Thanks Alot for the info guys..
the mod works great
the only thing i noticed is if i lock my diff. into 4HI first, then i hit the locker, it will not engage. Its sitts there and blinks. I have to engage locker first, then put into 4 Hi to make it work. kinda weird..
thanks again

blue wire?

Ok after a bit of searching around (here, customtacos, etc...) I didn't find a whole lot about the blue wire mod. just this:

Find the 4 lo detector switch on the transfer case and just jumper it one pin to the other ala paper clip. Has the same effect as the gray wire mod, no cutting involved.
anybody know of a write up? seems easy enough, but today wouldn't be a good day to fcuk something up, so I thought I'd double check.
thanks fellas

also, is this a valid concern?

Every time I read about the 'blue wire mod', I hear that it fools the ECU unit and can cause problems with the shift points on the automatic transmission. The grey wire mod bypassed this and made it possible for all models.

I do have the manual transmission, but I still dont think I want to be fooling my ECU.

Any thoughts?
his question never got answered and I too have a manual.

It's not a "blue wire", its a "blue PLUG mod" - just in case that wasn't a typo.

On a manual, the ECU does not control shifting, so it is irrelevant. As for the different ECU's around the truck, one of them wants to only let you lock it in 4-lo, so you HAVE to fool it if you want otherwise. The only other ECU you need to worry about is the anti-lock brakes one, so if you have ABS, do the grey wire mod.
