Default 2018 F150 ignition problems

Update: apparently removing power to the ignition blows a fuse in the passenger well. Replacing that fixed the problem.

So I was messing with the ignition wiring on my 2018 f150 trying to get the damn thing to stop beeping at me and I don't know how but I guess I messed something up. I was unplugging each of these wires one at a time to see if any of them was for the timer (FYI the middle blue wire disables the chime with the ignition off but not on) and the 12v yellow power wire accidentally got unclipped. Now I can't get anything to turn on even after clipping it back in. Don't know if its not getting power somehow or if I might have messed up the key programming or something else.https://i.imgur.com/qGv3llU.jpg

Best I can tell I think the wires are (top to bottom):

Starter

Accessories

Keysense

12V

Unknown

Ignition



Also If anyone knows a way to disable the damn chimer I would love to hear that too.

I always tear apart the ignition wires in my brand new truck. Even if I have no idea what I'm doing.

Try disconnecting and reconnecting and making sure the metal is seated correctly and contacting

If the yellow wire is the hot wire and it touched something metal it would blow the fuse, that is what it is supposed to do by the way.
