The 2006 service manual is here:

The wiring diagrams are section 8W, there's a subsection on "Front lighting" (8W-50) which includes the hazard circuitry.

p.s. i see there's at least one typo... on page 8w-50-2 they have two different colored wires both going from the fuse block to splice S351.
Page 8w-50-5 has the correct designations, one each to S351 and S352.
S351 and S352 are next found in the rear lighting section, page 8w-51-5
On a quick scan through 8w-50 and 8w-51, i don't see where they actually
get the wires to the front turn signal bulbs.
