    I was wondering if anyone has done this swap?? I just bought a 06 Tacoma Differential with a locker that i would like to install into my 05. The bad part is that they did not have the wiring and i have no ideas of what is needed. Can anyone help?

    I looked into this a while back, the pre runner and sport share the same rear end, the sport has the LSD. The off road version is a different rear end.
    Supposedly the sport/prerunner rear will not accept the stock , off-road locker diff. Your best bet is to get an aftermarket locker. It will require a diff/tranny shop to align your ring gear and other workings inside the rear diff. And with aftermarket... do you want an air / maunual / or electric type? Air might be good, use can use the compressor to air up or whatever, but it will cost more. Figure at least $900 to get started and maybe a few more hundred in case there are problems. good luck

    did you buy the whole differential?? if you did then you need the switch, i believe the harness for the switch is in the cab already just not used in the trd sports, then youll need to see if theres a plug along the rear that connects to the locker, your probably missing a small harness in the rear

    In order to use the Off-Road third member (locker) you will have to swap your 8.4" housing (PreRunner/Sport/4x4 non-TRD) axle housing with a TRD-Locker housing.

    Like LBtaco and oakleyTRD mentioned, You best bet is to use an ARB locker. You will save money in the end and have a much better locker over stock.

    Then swap, wire, and your good to good. You can get a wiring diagram for the locker from the FSM and run a simple switch to the cab if the harness is not already installed, or other harnesses are needed and cost prohibitive.

    I'm sure someone will chime in with information on where the factory wiring harness is located. If the vehicle is prewired, logic would lead me to believe that it is going to be located near the rear end and should be easily located with some looking around. Take a look at the connection on your locking rear end that you picked up, and you will know what you are looking for.

    Here is the wiring digram for the 05+ factory TRD-Locker on a 2wd setup. I am not sure on how extensive the factory wiring is for non equipped trucks, hopefully we can get some comments from people with experience on this. If your truck did not come with a harness, you could probably pick up a Pill for the connection at the diff., which would allow you to wire the diff. so it will lock whenever w/o the safety features (for simplicity) but it would not be advised that you turn your lock your diff @ speeds over the factory set limits. (5MPH)

    I've looked into this as well. I called my local dealership to get an idea on how much it would be to install a factory Off-Road E-Locker onto my Sport.

    The guy said total would be about $3000 including labor.

    Like mentioned, better off installing an ARB locker onto the rear!!!
