    Anyone done this on a 2wd 3rd gen?? I already have an AC60F trans but going with 1ton axles instead of the stock front setup. All I would need is the FJ tcase and then wire it up correct?

    random stuff. Oh! and converted to non ADD 4x4.
    Fj transfer case does not require wiring to work. The case has 3 switches(those are the 6 wires coming out of it, 2 for 4h switch, 2 for N switch and 2 for 4L switch) that connect path to ground for the 4x4 ecu to do his thing and for the lights on the dash.

    Yeah I still can't get the damn gear oil smell out. I'm going to have to sacrifice a Saturday and tear everything out and start again. Flex tape and rtv but it's still coming through. Not sure if I spilled some somewhere like it's just sitting somewhere I can't see lol

    I ended up enlarging the opening so I lost the snap in points for the wire. It's a good thought though. I think the boot would have been pretty scrunched up if i did that.

    i used the wire in mine. but the second shifter for mine is for a crawl box. it just moves up and down and has no side to side like the FJ tcase so i didnt have to open mine up and was able to reuse the wire. mines not really scrunched up tho.

    Question on sensors...

    Swapping cases on a 2007 regular cab. The stock t case has two detent sensors on the shift mechanism. The fj case I'm swapping in has three. Two are on drivers side, and one on drivers side. Which ones go where and do I just leave one unplugged?

    On speedometer sensor...
    My truck has the sensor on the case. I was a little um, ham fisted taking the sensor off. Is there a specific sensor I can order to attach to the fj case? It looks like it has a provision for a sensor? Orrrr am I stuck ordering another rear output cover for my truck and swapping it on? I currently have 4.88 gears and 37's, so it may be a good opportunity to get a more "correct" speedo gear anyway. I'm about 6" off at highway speeds.

    EDIT: my impatient, hamfisted results

    for the tcase sensors, you will replace 2 of the 3 with the 2 from the stock tcase. one left one right. dunno which ones are which tho. leave the 3rd one on the fj case where it is tho. it keeps oil from spewing out

    The speed sensor does not come with a gear. Or at least mine didnt. You need to swap over the gear from your broken one. If i still have it, I think there's a brand new 5 year old AC Delco sensor laying around my garage I can send you. I thought mine was bad so I bought a new one but it turned out to be a bad harness. I'll check when I get home tonight.

    @gtrotter07

    I lied its beck / arnley but at least I remembered the box was blue. I installed this briefly but when my speedo wasn't fixed by the new sensor, I traced my issue to the harness and put the original sensor back in. I'll give you a good deal on it if your interested.

    Question for those of you who have pulled the back of the TCase off, I have a leak on that back end on my transfer case. Can I pull the back end off with it still mounted to the truck, or do I need to drop it? any other tips or things I need to know?

    Here is where the leak is:

    I think you need to pull the entire case. Pulling the case isn't too hard. Lots of videos / tips available on how to do it.

    got 2 tcases
    Taco stock with a hole in it for spare parts
    Automatic FJ one

    need to figure out how to twin or triple stick
    2LO
    And if the broken Tacoma case is what’s needed for building a NWF ecocrawler

    question about 2LO
    Does it have more functions than maneuvering a trailer?

    like burnouts and donuts? or just do that in 2HI 1st
    For example hypothetically in Mexico how would you swing the truck around?

    say you want to do a quick tight u turn and drift it in the rain
    Don’t get me wrong I could easily drift my truck stock any which way on 31’s

    but on grippy 35’s it doesn’t seem as excited to be doing that any more
    I imagine 2Lo could do that but is not practical because you have to stop, change gears, stop again, change again
    Not realistic
    Versus 1st gear, hit the gas, swing 180 and go
