Toyota locking axles are great choices for axle swaps. 8" E-locker differentials are strong and versatile. Wiring a Toyota E-locker differential to work outside of its donor vehicle is possible but not as simple as just splicing a few wires.  DIY instructions for this modification have been published for decades. For years we had been selling sections of factory Toyota harnesses to be converted into universal harnesses. That process involved cutting and splicing the ends on-to six-lead trailer wire. Not only is trailer wire expensive, it isn't even the correct wire gauge. When added up, the cost of a DIY harness can easily surpass $150. Put simply, making your own harness by splicing into an OEM harness is a pain in the neck! 

But several years ago Low Range Off-Road embarked upon the goal of creating the best purpose made wiring harness kit for Toyota E-Locker axle swaps. We wanted an easy to install harness that requires as little modification to the vehicle as possible. After a few revisions we have what is now the Ultimate E-Locker Wiring Harness Kit.

Our harness is made up of OEM grade cross linked insulated wire.  We use wire gauges that match the factory harness. Harnesses are 18 feet long and available for both low pinion and high pinion differentials. Please verify the plug shape on your differential to make sure you get the correct harness plug. Some newer low pinion differentials may have high pinion plugs. Harnesses come with either "Front Locker" or "Rear Locker" labels.  

Compatible Toyota electric lockers are found in the rear of 1996-2015 Tacomas, 2007-2014 FJ Cruisers, and 1996-2002 4Runners. High pinion front axles can be found on 1993-1997 FJ80 Land Cruisers.

Harness is supplied with (2) 15A fuses: (1) ATO and (1) Mini fuse.

Low Range Ultimate Harnesses can not be used on 2016+ Toyota Tacomas.
