Grey wire mod

It's not going well. I took it off again and took it apart. It was corroded and the arm couldn't even move. I got it moving again but it still doesn't work. I think the worm gear is also stuck. Ugh.

 

Shit, sorry to hear man, its just getting worse as you get deeper into it & you say its stuck ? If you can't free it up , your probably done because both surfaces with be pitted/corroded/rusted/etc: does the servo motor still work ?

 

I unfortunately and stupidly enough didn't try to run the servo unassembled to see if the worm gear moves freely. It's what I am going to do today. When I tested it assembled after I freed the arm I felt the servo get warm but no movement. We'll see what today brings.

 

Yeah I didn't get to work on it today, but tomorrow is another day. At least I can take my locker on and off in 5-6 minutes flat.

 

Headed to the shop to do this now! Thank you for the pictures and everything!

 

Has anybody tried this mod successfully on a 2007 TRD?

 

Only works on 1st gens

 

I finally got around to doing this.... I don't know what I was so scared of. This literally took me 6 minutes from start to finish (which included putting my floor mats in and a quick test of the switch). Great write up.

 

Did this to mine N Love it!

 

I'll tell you why, because like me I'm reluctant to start mojo'ing the electrical, especially with electronics our trucks have, when I finally did do it I kicked myself for waiting so long to do it, easily the best,easiest smartest,cheapest MOD going for a 1st gen. 4x...

 

Finally Fiiiiinally did this. Wanted to get my locker working first. Great mod, and will be a big help in cycling the locker on and off- gotta "use it or loose it".

 

Great mod, and even better ttora locker rebuild, my locker doesn't work either, I just wish my actuator case was only corroded as his was

 

Same. This is as far as I got with the project:




Ran out of time that day and had to throw it back on till I can get time to play with it again.

 

Tagged for later. Thanks for posting the info

 

Not sure how to upload more than one pic at a time, seems to only upload the last one, anyway, here is mine, cover was corroded way worse than any others I seen, and before I even tried to take it off I noticed the cover was cracked in 3 spots and it was cracked all the way around the output shaft. This is after I got the cover off and the output shaft stayed in the middle. Anyone know if someone makes an aftermarket locker that bolts where this one came off? I can't even make a new cover an use this one bc I can't even get the worm gear to move, I couldn't even see it through the corroded aluminum. No posi marks for me

 

Also called the dealer, a replacement up here is $1400, gonna cut a plate and bolt it in over the hole in the rear diff for now

 

Had a fun time wheeling in both high and low with the locker on. What top speed do you guys do when locked?

 

I never wanted to do this mod because I was non fond of cutting a factory wire! So I figured out a way to do it without cutting it. Actually two ways. First way remove grey wire from the modular plug then I found a modular plug in the same area not in use I think its for the factory security system. So I removed one of the wires from the unused modular plug and cut it back 6 in. Then inserted it were I removed the grey wire from the 4wd mod plug and put a ring terminal on other end. When I reinstalled the 4wd control box I just put the ring terminal under the bolt for ground perfect and neat! Second way is remove grey wire from modular plug put shrink tube over end to protect. Now open the black 4wd control box and slide out circuit board (very easy to do) Now on the back of the plug on the circuit board on the bottom row of metal strips from plug solder a jumper to connect the two middle ones. One is from the grey wire the other is a ground. this is a very neat and professional way to do it! My only word of caution is taking the wires out of the modular plugs is a BITCH.
Enjoy

Thanks for the write up. This was so simple. Why doesn't Toyota make it standard to use the locker in 2 wheel and 4 hi?

 

More than likely liability issues. Also if you try to engage the locker at any speed higher than about 10-15 mph it will strip the gears out on the motor.
