Also just a simple google search of wire diagram symbols will answer what each squiggly line is

Traced all the wires and couldn't find anything wrong with any of them. Yesterday the key would kill all power like it's supposed to. Now it's back to the dash lights and cablights etc etc staying on after turning key off. The 2 amp DLIS fuse also quit blowing but truck still won't start. I'm at my wit's end.

Almost sounds to me that something is shorting out the BCM and possibly killing it too. You may need to check all of the circuits coming out of the BCM that the DLS fuse powers.
What about putting a light bulb in line with the fuse? Something that will limit the current to a safe level then probe the wires and measure the voltage. When you remove the short or disconnect the bad wire the bulb will drop in brightness or go out.

I'll get the light bulb rigged up tomorrow. This has been a going on for almost 2 months. 2 shops have already looked at it and gave up. I'm ready to call it quits but so determined at the same time!

You check the under hood fuse panel? They warp and cause issues or get mice in them...

Just to update everyone. I have put hours on hours into this thing and I'm finally calling it quits. It's going to another shop on Monday that has even agreed to let me shadow the mechanic while he diags and hopefully fixes it. I'll update everyone with the fix. Thank you to everyone who has helped
