1998 Jetta TDI no start no glow no MIL

1998 Jetta TDI, Crank, no start, no glow indicator, no MIL. Load
reduction relay 109 swapped with new spare. Swapped relays marked 53,
both work.
No change.
Physically checked fuses, reseated fuses and relays.
Battery connections clean and tight.

Bentley wiring diagrams and such are somewhat different than the
configuration the vehicle has, relay numbers and function not always
correseponding with reality

The glow/mil indicators occasionally come on when cycling the key
multiple times or poking at fuse/relay block, car will start and die
within moments. I'm assuming that it's a relay failure but without
accurate wiring diagrams, diagnosis is particularly difficult. I've
identified a few of the relays as standard systems, some of the others
remain a mystery.

Anybody have a clue where to get accurate diagrams and any
ideas/experience on the symptoms?

Here's a table of what I have in what position
Looking at fuse block, regular fuses on bottom(not shown), undocumented
fuses on top(shown).

Replaced last year. Key on: No MIL, no glow indicator, other indicators
act normally. Suspects: relay, ignition switch, ECU, immobilizer if
equipped.
#30 battery bus in relay center has power, all systems in car seem to
have power.
Unable to locate a point to check #15 (got minor frostbite, gave up)
switched/relay powered circuit, not even sure how the ECU is triggered
by the ignition switch. Wiring diagrams are just plain wrong for this
car. Does anybody have an accurate map of the relay center and their
control numbers? The car also has factory alarm, so I assume it has the
immobilizer function, does anybody know if the immobilizer cuts the MIL
indicator when active?
