On 35s Elocker rears take a surprising amount of abuse. You can use the parking brake cable from the tacoma and make mounts to connect to the actuator arm on the frame
Same setup thats been under my 2nd gen for 10 years. Have taken out a R&P and a side gear but they were "somethings gotta give" moments of 6000rpm double low bouncing up a waterfall with a full body 2nd gen at 4psi...
ARB is probably stronger but electric has been 100% reliable in the locking/unlocking. Just used the LROR switches with some trailer wiring down to the frame. Easy-peasy-no pneumatic leaks-y.
