Question 1995 SC300 MAF Wire Labels?

Does anyone know the function and corresponding position/color of each of the 5 MAF wires for a 1995 Lexus SC300 (5 spd manual trans) car? I don't have a lot of experience with electrical diagrams and was hoping someone could shed more light on this section from my service manual:

hey, did those two wires work out for you? im guessing your wiring in the IAT for aem with those?

cause it differs from DaveH's diagram


according to his (B45 and B65) the wires on the sc300 should be Y-B and BR1

looking at my maf right now,
and it has 5 wires, not 4.......

anyways I wire up one to the brown wire (looking at the plug with the notch on top, its the one on the left)
and the second wire the the yellow/black wire (its the one thats 2nd to the left)



anyways
I am using a cal file from another NA-T with 440's
but my Air Flow is maxed out full red bars
anyone know why?
