FOR THE WIRING MOD.....
You will need to access the Wiring Harness at the
Differential Lock Control Unit (DLCU). It may be easier to do this by removing the Driver-side Door Seal and the Knee Knocker Panel under the Steering Column.
Perform the changes on
This Schematic. Due to new security standards at Google, I may have to grant access. It's been hit and miss whether I have to do this. Operating Instructions and Warnings are on the Schematic.
It allows anytime engagement of the factory installed M226 eLocker in 2HI and 4HI, without the 4 mph limit, without the associated warning lights, extra switches, and extra wiring of the 2005 Off Road Magazine / "Austin Mod". You will still use your factor Diff Lock switch and have indication on your factory Diff Lock indicator.
FOR THE PLUG N PLAY MOD.....
It installs in under two minutes, or as fast as thirty seconds (per some reviews).
It consists of locating the Differential Lock Control Unit (DLCU), near the hood release on Xterra's and Frontier's, near the rear bulkhead near the jack on 2nd gen Titans (not compatible with diesel Titans), unplugging the factory wiring harness from the DLCU, plugging this unit into the DLCU, and plugging the factory harness back into the included unit.
Included instructions here.
This modification gives you the ability to lock the rear differential anytime as with with ARB Air Locker and Eaton E Locker. If you are uncertain about when to lock the differential, refer to the factory parameters of 4LO and under 5 MPH.
ENGAGING THE LOCKER UNDER THE WRONG CIRCUMSTANCES CAN LEAD TO DRIVE TRAIN DAMAGE
