How do power extenders work now?

[JDub]

Used to be that you had a power extender in your pack and it would show up when you pulled on a power cord. Now: 

1. Can't get the "pull power cord" behavior to work. 

2. Can't place extenders on the ground by themselves. 

3. Can't attach an extender to a plug. 

So how do I run a power cable down a hill now?

maybe you figured it out by now but the slow way: put bundle on ground and activate. takes out one extender.

faster way: place bundle in backpack aux slot(top slots), grab a cable, drag to desired position and hit aux hotkey.(default  C or V depending on slot)
