Well, I thought I've seen it all with the suspension and trans faults from blown tail-light bulbs but this one takes the cake.
Shorted circuit board in the driver's side (LH NAS) vanity mirror is the fault of all of my problems. It will take me a month to get the truck back together (exaggeration) but I am now confident in almost all of the wiring in my truck with zero corrosion issues and wiring looking really good throughout. I was consistently getting the battery saver relay fault which by the schematics has the left vanity mirror in the loop.
My issue was, when I was shooting wires and checking the board, it works great and everything checks out when the mirror door is open. When the mirror door is closed, it consistently blew the Fuse 1P (10 amp) and overheated the Central Junction Box (CJB-fuse box under the glove box) and the Battery Saver Relay (R250). I believe the same thing was happening with movement of the sun shade, but most definitely with the door closed as during most of my troubleshooting I had both vanity mirrors open with bright lights shining and no indication of any short or failure.
The problem I believe is in the circuit board behind the mirror, although it appears to be intermittent I am able to duplicate the problem by opening and closing the vanity mirror door with an external battery connected. With the mirror disconnected at the A-pillar, everything works perfectly in every fashion.
I'm really at a loss for words as it is hard to believe this vanity mirror circuit board can shut down half of the truck (seats, mirrors, radio, amp) and most importantly the main battery protection.
The pictures show the wiring down the A-pillar under the airbag and the small two-pin connector at the swivel for the sunshade.
Hope this helps someone in the future!
