Installing an amp and subwoofer to my 2010. Everything on the install went fine except for the remote power wire that runs from the amp to a switched power source. Looking for a wiring diagram or identification of the radio power that is hot when the radio is on and cold when the radio is off. A couple of sources have suggested it is a blue wire. The only blue wire I've found on the radio didn't work. Any thoughts on the right wire and it's location?

Thanks,

 

I used a tap a fuse (I think that’s what they’re called) and connected it to a fuse in the fuse box in the passenger side footwell area. I forget which one I used but it was easy and amp turns on and off when truck is turned on and off. Only thing is the tap a fuse sticks out a bit so the cover on the fuse box can’t go back on but everything is still covered by the kick panel.
