Total Locker Control - This allows complete control over each locker independently. It is a simple modification as well. It is reported that the locker indicators on the dash will simply blink whenever you use this modification. The computer may also set a trouble code but this has not been confirmed.
To control the rear locker you simply need to ground pin 42 of C1 from the TIPM (violet/light green). To control the front locker you simply need to ground pin 41 of C1 from the TIPM (violet/dark blue).

Like in the other above method the FCM monitors it's locker relay output for any unspecified draw or source. The FCM will set a DTC or a tell-tale in this event as well. Your dealer WILL be able to see it when you service the Jeep. Probably bad for your warranty.
Consideration: This method may not be subject to the 18 mph speed limit. Locker operation will continue until switched off.
Consideration: There may be problems with the lockers on and the ESP system in full effect. The ESP monitors steering position, wheel speed, etc. When you would make a corner with the rear locker on both wheels will maintain the same speed. The ESP may misinterpret this as a wheel with loss of traction and cause the system to try to compensate using throttle control and ABS.
