12v always on mod

does anyone know how to make the 12v ports where you charge your phone stay on when the truck is cut off?? I would like to wire them so they all stay on anyone who can help me figure out how to do it step by step, I'm clueless when it comes to wiring. if anything, I just want to make it so at least 1 port stays on... any help would be appreciated...

 

You would have to wire the port directly to the battery.

 

Could make a dedicated circuit with an "add a fuse" adapter.

 

What size fuse do i put in the add a circuit if i wire it directly to the port

 

It currently has a 15 amp..
This fuse is located under the dash on the driver's side.

Test it and see if it is hot with the truck off.

 

Get into the dash behind the head unit, there is a red wire that is always hot back there just
Splice a wire over to a cigarette lighter or usb whatever you want to be on.
Did it on my truck when I replaced the radio.

 

The Battery hot wire for the HU is either beige or violet depending on where you intercept it.



It will be violet at the HU.
Connector J133 Pin 4 in the HU

 

Where are yll finding these diagrams?
