that turbo moost sensor is not the map sensor for the engine
im pretty sure the 1j have a seperate boost sensor for the gauge
the wires are white orange and another colour
not to sure what the wire colors are for the engine map sensor
if i get spare time over weekend ill chase it up
i think light green with red trace maybe is the signal wire
ithen brown should be sensor earth as thats toyota common colour
and 5volt supply i think is yellow
