I just finished a soarer 1jz swap into my 98 sc300. The map sensor plug is missing. I think I plugged it in right but I am only getting 5v to the blue with red and 0 volts to the green with black. Can anyone tell me the order the wires plug in and also which wire is ground, 12v, and 5v? Thanks

 

Nevermind, got it all figured out. Please delete.

 

I don't know the order but I know toyota wire colors.
lavender red is sensor +5v
brown is ground
the other one must be the sensor signal wire (output to ecu)

to actually test the voltage on the pins with the ignition on, the combo that gives you +5v, the wire on your voltmeters red lead is the +5v, and the other will be ground. (if you see -5v, then swap the leads around)
now move your red lead to the other wire and you should have around 2.5v with the engine off ignition on on a stock map sensor. this is your signal wire that returns to the ecu.
there is no 12v wire, just +5v, signal and ground.

edit: had to figure out the order for my na-t project using 2jz map sensor.
from back of connector with tab up, it is: (+5v - lavender/red ) (signal - green/black) (ground - brown)
