Hi,
DF039 airbag/seatbelt driver side circuit
DF056 injection, air flow sensor circuit

l also can't find where 12v feed comes from. Haynes manual is useless and nothing on the net.
You will have to follow wire back to source, but l have a feeling it may go to the pcm.
l would look there for corrosion or bad contacts at connectors.
Maybe as a test, you could give the maf sensor a live feed from battery and see if it runs better.
lf l find anything to help l will post again.
