Gen 2 rear Locker ECU part number or pic of location?

[MontyG]

Hi all. I have a 95 Montero LS. I got lucky and found a gem at local junk yard, a 94 SR. I got the 3rd member, left axle shaft, r/d button, and compressor, but for the life of me I could not find the rear locker ECU. From what I've read it is in the left rear quarter panel. I removed the huge trim panel and dug around but no luck.

I'm hoping someone can give me a part number, or better yet a picture or good description of where I can find this thing. Thank you in advance!

Google may have answered the part number question for me: MR276183? Not sure if that is the ECU I'm looking for but if so I do recall seeing that part while digging around. Hopefully the car isn't crushed before I can make it back!

If someone can confirm it would be very appreciated. Thanks!

Yes.. its behind the rear drivers side panel. Unfortunately, that 3rd member wont bolt up to your LS housing...

Eek, did not know that... I got all the parts but I've been told by the at home boss I can't work on it for a while . Different size housing? I read on 4x4 wire (http://www.4x4wire.com/toyota-secti...factory-air-locker-into-a-genii-monteropajero) that it will bolt right up with the left axle shaft but maybe I just have the wrong year for that?

3.0 6G72 = 9" rear end

3.5 6G74 = 9.5" rear end

The '94 SR should have a 3.5 6G74 while your '95 LS should have a 3.0 6G72. You could swap the entire rear axle, but can't transplant a 9.5" third member into a 9" rear axle housing.

Hopefully you can still go get the housing and install everything you removed.. Hopefully you didnt cut stuff off like brake lines and parking brake cables. To add to na3s' correct info on diff sizes, the smaller third member thats currently on your truck bolts on with 10 nuts/bolts, while the bigger 9.5" rear end third member mounts with 12.

Dang I should've gotten the whole axle then! Nope, too late, car is crushed now

Thanks for the info, guys! SO glad to get the help before I started taking things apart on my car! There will be some parts for sale if anyone needs rear locker parts

If you have the locking 3rd member w/the associated bits and it's the gearing you need, it shouldn't be too difficult to find a rear axle to swap it into. Fairly certain even a Sport rear axle housing would swap so long as it came behind a 3.5.

 

[MontyG]

Whew, thanks! The sports seem much easier to come by at wrecking yards.

You can operate the air compressor for the locker totally independently, it just needs 12v across it. I've mine wired to a switch on the dash, allows it to work in 2wd and 4h as well
