Auxiliary lights

[servantsalesmen]

'm thinking of adding auxiliary lights in several places to my 04 2500HD 6.0. The truck does not have a plow prep package.

 

I'm hoping to add an LED bar up front. How should I wire it? are there any preexisting but unused auxiliary circuits that I could tap into? It would just make it cleaner that way I suppose. And the truck does have factory fog lights.

 

Secondly, I would like to add lights for backing up. I have concluded that either just tapping into the reverse lights or wiring up a trailer harness and keeping it plugged in would be easy options. Am I wrong or am I on to something?

 

Lastly, I'd like to add in some more bed lighting. Could I use the circuit with the roof mounted cargo lamp and wire in another set of LED'S on the same switch?

 

I know it's a big post but I appreciate any answers! Thanks
