I kinda new to this board and I was a little surprised to see that I was the only one that had modified the rear locker on an FJC. When I got it that was the first thing I sought out to do. I did some research, here and other boards and it all seemed like it should be similar. After I got it, board members wanted to see the dash lights to prove it so I posted some pictures of the dash. I was asked to do a wright up of what I did so here goes. I'll add some pictures later when I take it back apart.
You can get to the 4WD control module without taking the kick panel off but its a little easer to do with it out of the way.
First you remove the driver door sill, it just pops up. Pull and wiggle smoothly and slow so you don't break any tabs.
Then move to the foot rest on the floor by the kick panel. Same way, wiggle smoothly and slowly, pull towards the rear.
Next is a little black screw looking thing that the foot rest was sort of hiding, it just twists off lefty loosie.
Next is the kick panel, just pull it strait back towards the rear.
Now stick your head under there and look way up and near the firewall. You should see a little blue box, a little larger than a deck of cards. Thats the guy.
In that magical harness holds the wire that gives you the locker anytime you want it. The wire is white with a BLUE stripe. There is a green wire on one side and another white wire with a BLACK stripe on the other side of it. Be careful and cut once and look many times to make sure its the white wire with a BLUE stripe. I cut about 1 1/2 to 2 inches down from the connector. I used one of those splice type connectors so I wouldn't have to squeeze my ham hands up in there with a striper tool. The wire size is 18-22 gauge if your going to use the splice type connector. 6 inches of extra wire should be fine for the job. You'll want to connect it to the white wire with the BLUE stripe coming out of the Blue box and then ground it. You can ground it to the 10mm screw that holds the blue box up there. Then take the other open section of wire and fold it over and stick it back in the wiring loom or you can just tape it up, what ever you feel comfortable with.
I'll pull it back apart this weekend and take some pictures so everyone can get a better idea.
The locker will engage any time you want it to as long as your 3 MPH or less. Once engaged you can go as fast as you like and it will disengage at any speed. Wile engaged it also disables ABS, VCS and Traction Control. Great for those guys that like to do donuts or get the rear end out in the corners.
Have fun,
Will

The reason for the A-trac+locker mod switch is so I can have or not have traction control in 2WD.
The blue box is the 4WD control module. Cut the White wire with the BLUE stripe and ground it from the blue box.
