Wiring questions for 2010 Crewmax

[lawfarm]

1. Anyone know a good location to tap into the clearance lights in the cab? I'm going to add roof clearance lights, and need to find a spot where I can tap into the wiring harness to power them. I'd like them to be wired to the balance of the clearance lights. Any suggestions?

2. I'm also going to add a set of Hellas behind the grill. Any suggestions on a good place to tap into high beam headlight power? Anywhere other than immediately behind the headlight plug?

3. Finally, I'm going to add a line of fire rear LED light strip. Any suggestions on the best way to wire it in? I don't want to just have it plugged into the trailer light plug because of where it is on these trucks. Any suggestions? Is there a way to get a plug that will plug into the factory harness where the trailer light plug connects?
