Where are you tying in for auxilary power stuff?
Where are you tying in for auxiliary stuff like lights, radios, and the like on something as new as a 2012? I see what appear to be two fused "auxiliary lugs" off the power distribution panel under the hood? I'm trying to avoid cutting into any factory wiring...
What about an source for "ignition on" signal that I can run a relay with? If I can get hold of an "ignition on" signal, I can pull from the battery and trigger things through a relay using the signal source.

Title says NBS but it actually is for the NNBS pickups. Not sure about the 2012's but i have the parts ordered and will hopefully be doing this to my 2008 later this week.
As far as the two lugs off the fusebox. One (i think the larger one) is for a brake controller. The other is a constant on 12 volt (have to put a 40 amp fuse in before you get power off the lug, its meant to provide power through 7 pin plug for a camper)

Cool, thanks for the link.
I'm probably going to stop by the dealer and talk with the service guy, find out if there is anything I need to know. I'm wondering if I already have some of the wiring in place because of the plow prep package? Supposedly some wiring ran fore and aft, plus the beacon wiring/switch.
I also need to ask them where the camper wiring is located under bed...the $35 add-on for an in-bed wiring harness. I like to use the trailer wiring for auxiliary lighting because its fused separate of the truck's wiring.

sounds like you've got it kinda figured out, but i was gonna say that on my 08, up behind and to the left of the brake pedal, theres a distribution block with a plastic cover on it. Not really sure what they're used for (possible iTBC plug-in) but i found a switched source that turns on w the key and shuts off when the ignition is killed and then door opened. I used an 18 gauge female end of a flat quick-connect terminal, cut half of it off and just used one side of it to slide onto the pin, I did the same as you're thinking and just used it as signal wire for a relay, which now runs my interior lighting (led strips under the dash and under the rear of the front seats) and also my amplifier power switch.
edit: I lied, i forgot i actually moved the power source for my lighting to the yellow wire coming from the dimmer switch so they would dim with the dash lights and such. they were ridiculously bright and actually decreased visibility to outside at night haha.

On my 04 NBS truck I tap the IGN fuse for key/switched 12v.

OK, reviewed the fuse panel diagrams in the OM and noticed there are several "SEO/upfitter" slots...Dodge had a "Body Builders Manual" that explained what all those circuits were and what the intended use was for. Does GM have anything explaining those extra slots?

We should get an admin to sticky this thread or at least the post with the pdf link on it, as I'm sure this has been brought up before now and that's the first time I've seen that file...

On my 2011 I installed two fuse blocks under the hood to add power accesories through.
I used Marine rated power distribution/fuse panels each with 6 open slots, one I ran directly from the battery and the other is run through a relay thats switched by the ign.
So far I've only added an underhood light and back-up lights to the direct battery source and a CB to the switched source.
I bought all my connectors and power blocks from Marine West.
