Replace factory elocker with LSD?

This guy already has.....

 

Interesting, so I guess you would need a transformer to provide the correct voltage.

 

A transformer can only change voltage on AC circuits, not DC.

A resistor or a Pulse Width Modulating (PWM) power supply would generally be simplest solutions... ASSUMING voltage is a problem. It might be fine to put 14v on it, but I am not going to try it at 14V and I am not going to recommend it to someone else when it clearly is outside the proven safe boundaries.

Here is an example of a resistor type installation (in this case to use an OR rear end with locker on a sport).

And let me be clear, it is by NO means impossible to do anytime lock, it just isn't easy to do the way I would want to do it (electro-mechanically) and definitely beyond my skill set to do elegantly (using a microcontroller in a OR/Pro). We know enough about the locker system at this point that somebody (not me) could now build a microcontroller solution to do it elegantly.
