If you dont want to cut alot of stuff using the relay, check out the "alternative locker mod"

 

Just unplug the locker from the diff. Then undo 4 screws and push the pin over. Dune! Lockers all day every day!

 

there is the one wire locker mod out there for the TRD OR's that trick the trucks computer into thinking its in 4LO. This will allow you to put the locker in in 2Hi and 4Hi

This does have a tendency to throw a code however, especially in 2HI cus the computer goes, wait a second, how are you spinning the rear tires so much faster than the fronts... hmm front diff actuator musnt be working cus i am in "4lo"

 

Link to the one wire mod ?
