adding a light bar
I'm in a bit of a pickle right now, not much time to search all these pages, I need a 12v IGN source to wire my light bar switch too!?? So I need it off when the vehicle is off , on when vehicle is on. 2016 f150, any help would save my ***!
Add a fuse easiest route...Take your pick...

thanks I used an add a fuse to the 4x4 module fuse,after testing them all it's one of the few that worked how I wanted it, is there any risk to tapping I to this? Again, I used an add a fuse

Amps?
I assume all this does is goes to a switch. That switch then goes to a relay coil. The actual power that runs the lights should come from the battery through it's own fuse to the relay. That is the safe way. As then the current draw on the add a circuit is minimal few milliamperes. You can then use any existing fuse to tap into.

Not sure I understand the comment 'few that worked as I wanted'. They all should behave the same. On with key per diagram.

I had tested all the fuses with a test light before you had posted your comment, what I meant was the majority of the fuses I tested were hot, even when the vehicle was off, there was only a couple I tested that **** off when the key was off, I'm not sure exactly all of them but the 4x4 was one that worked for me, and was also in your diagram.
