It's all in the owner's manual. It's the same as this, except as noted below:

A: Flash-to-Pass
C: Horn, Speed Control
L: Fuses 9 & 13
P: Fuses 2, 6, 11, 14, 17, U

No relay for hazards or brakes. The BOO gets power from Fuse 13 (thru Fuse L), just like the hazard flasher. So if the hazards work but the brake lights don't, the fault is on the back of the underdash fuse block.
Walk softly & carry a BIG SIX ! ! !
