No problems reported so far with this mod?
Like OP mentioned above, no issues. I have had it unplugged for about a month or so without any issues or decline in gas mileage.

Did unplugging this make the battery light come on?
Sitting in traffic earlier today, my voltage was down to 12-ish. I shifted to neutral and revved the motor and it climbed to 14. Maybe the cooling fan drug down the voltage? Either that or my alternator is getting weak and the extra heat from idling reduced it's output. Whatever, at least it's not dropping voltage while driving.
on the 07+ we have this regulating system (Regulated Voltage Control or RVC) that basically controls the alternator when it sees more/less drain on the battery.
Being that I have a decent sized stereo as well as HIDs (with the relay harness) on my truck, I looked for a way to turn the RVC off. There would be points while driving that my HIDs would start to flicker because the ballast weren't getting 12 volts. I thought it was the ballast and swapped sides and even purchased new ballast with the same results.
Well, there is a wire connection on the negative side of the battery that controls this system. If you unplug it, your alternator will continue to charge and will stay around 14v while driving. I've had this unplugged for almost a month now with no issues what so ever. No more stereo drain, no more flashing of my HIDs, nothing. I haven't seen any consequences of disconnecting it either.
Here's a few pics you can see the plug and the wiring to disconnect. I put some electrical tape over the connections so they don't rust or get corroded or anything.
