There's a light blue plug that comes out of the passenger side of your transfer case. It has two wires, I just interrupted one of them with a switch. I actually went and got a push button shift knob from a scrap yard and used that as my switch.

Wouldn't this plug be the easier of the two mods anyway, especially for a manual tranny? I would rather unplug something than cut wires while I'm under warranty.

confused

I hate being confused Hopefully someone can clear this up for me. I have a 2004 manual w/ TRD locker. I unplugged the blue wire on the driver's side of the t-case/transmission. Now I can shift into 2-lo w/o 4wd kicking in - perfect!

I don't know if it's coincidence or not, but now when I try to engage the locker, the rrdiff light keeps flashing. I've tried the the usual pulling forward, turning, backing up, etc.

I'm just curious if unplugging the blue plug screws up engaging the locker before I dive into tearing apart the locker actuator. I have not done the grey wire mod.

Is there a different 2lo mod for a manual vs. an automatic? For some reason I had a hard time discerning that from all of the different posts in this thread. Thanks!

kinda fixed

Well, I guess I kind of answered my own question. I just plugged the driver's side blue plug back together and now the locker engages perfectly. Sooo...., what the heck do I need to do to get the 2-lo mod and still have my locker work?

Dick, I just read your awesome write up on that. I may do just that.

From what I gather from this thread, I need to do the grey wire mod in order for the locker to work with the 2lo mod, is that correct?

 

[cheez]

if all you had done was the blue plug mod, then you could have used your locker when you were in 2-lo and the 4wd button engaged (putting you in 4-lo).

That doesn't seem true, at least not in my case. I unplugged the blue plug for the 2-lo mod. I shifted the transfer case into 4-lo and engaged 4wd by pushing the 4wd button. The locker would not engage to safe it's life.

As soon as I plugged the blue plug back together, shifted into 4-lo (now 4wd automatically engages like it should) and pushed the diff button, the locker engaged almost instantly.

I then unplugged the blue plug, again shifted into 4-lo in 4wd, and the locker does not work.

Therefore, something is not letting the locker engage when I have the "2-lo" mod done.

That's why I'm wondering if I need to do the grey wire mod first in order for the 2-lo mod to work. Obviously I could do what Dick suggests to get around all of it but I'm hesitant since I'm still under warranty.

I can definitely hear and feel it clunk in when it does and the light stops blinking immediately. I tried everywhich way with the blue plug unplugged and the locker would not engage. As soon as I plugged the blue plug back together, the locker engaged almost immediately after I pushed the button.

I'll try unplugging the blue plug a 3rd time just for the heck of it. Maybe I'll try it out with the rear jacked up. Maybe this weekend I'll get around to doing the grey wire mod to see if that has any impact on this 2-lo mod.

I'm pretty sure an '04 is the same as any other Tacoma except the '05.

Mine did the exact same thing. You need to do the grey wire mod. After I did the 2-Lo mod mine wouldn't lock up until I did the grey wire mod. Did the grey wire mod and now it locks up perfect.

I love 2-Lo!

That's exactly what I was looking for! Thanks!

Wait a minute, did I read that correctly? If you do just the two-low mod, of course the locker won't engage. One of the checks that the locker ECU does is that the transfer case is in FOUR low, with the diff engaged. You would HAVE to do the gray wire mod for the locker to work in anything but four low.

I will update the write up.

That was my problem with the 2-lo mod. Even with it shifted into FOUR low (diff engaged) I could not get the locker to work. I think the locker just doesn't like something about unplugging the blue plug, even in 4-lo.

Cheez, I think you may be confused. The 2-low mod uses the blue plug on the PASSENGER SIDE. The alternative locker mod to the grey wire mod was to SHORT OUT the blue plug on the DRIVER'S SIDE.

It sounds like you have push-button 4WD, and so the blue-plug locker mod (on the DRIVER'S side) may not work for you, in which case you would have to use the grey-wire version of the locker mod.

I don't know how the blue plug on the DRIVER'S side might interfere with push-button 4WD, so if it causes you problems you may need to use a double-throw switch. But the grey-wire mod will over-ride anything done at the blue-plug on the DRIVER'S side, as far as the locker is concerned.

Yep, I do have push-button 4WD. I unplugged the blue plug on the drivers side as shown specifically in the instructions in the first post of this thread (so much for following directions ) It did make it so I could shift into lo without 4WD automatically engaging (as advertised) and everything worked like it should except the locker.

It sounds like I just need to do the gray wire mod along with unplugging this same plug and everything will work just fine, or something. BTW, I looked everywhere and did not see another blue plug on the passenger side.

Okay, I just did the grey wire mod. The grey wire mod does need to be done in conjuction with the 2-lo mod in order for the locker mod AND 2-lo mod to work. In other words, just unplugging the blue plug on the driver's side for the 2-lo mod makes your locker inoperable until you do the grey wire mod. I feel better now

Cheez, I think you may be confused. The 2-low mod uses the blue plug on the PASSENGER SIDE. QUOTE]

That is incorrect, at least for my 2004, V6, TRD, manual tranny, ext. cab. I just did the grey wire mod and unplugged the blue plug on the DRIVER'S SIDE and everything works perfectly now. It is the exact same plug that is shown in the directions linked in the very first post of this thread. There is no blue plug on the passenger's side.

I been waiting way too long to try this out. Just want to clearify that if you haven't done the grey wire locker mod, your TRD locker will not engage.

Although 2wd lo is great for teaching others to drive a 5sp.

That's how it was on my '04 manual
