Hi,
Looking through the schematics, I noticed all fuses (which jump around as far as the wiring) are powered via a white wire or a black wire from the fusible link box.
Do me a favor. Locate the white and black wires and check to see if power is going through them. There should be 12v at all times.
Next, there is a black wire that comes from the fusible link box and sends power to a 40-amp main fuse (pic 2) that is what powers the headlamps/DRL.
In theory, there is a problem with the fusible link box. See pic 3
Check these things and let me know what you find. Also, here is a link you may find helpful:

I will watch for your reply.
Take care,
Joe
