Hi again Joe

Please fell free to examine the circuit diagram here

http://www.dmcnews.com/Techsection/graphics/lockcircR1.jpg

It clearly shows that the fat red power supply wire is nothing more than 
the feed which is switched by the relays on the module. It is NOT the 
power supply to the module, that is pin 4 (marked "vio" for "violet") at 
the upper left. Trust me, I've re-built several of these and have a 
solid understanding of how they work. 

I actually recommended un-plugging both the harness and the red wire, because there is still a remote possibility of the relays "chattering" (perhaps going over a big bump) and powering up the solenoids.

I would recommend anyone who wants a srronger understanding of this device should look at the DMC News tech section where there's an in-depth description of this circuit's operation. 

I also completely agree that in its stock form, the lock module should NOT be used, even if it apparently works fine.
