okay, so iv searched and iv found a few different answers. i need a definite answer though.
i have a aem ems v1 in my sc300 with a 1jzgte.. im trying to wire everything up and this is the last bit im stuck on.
MAP SENSOR
GM 3.5 bar sensor:
On the GM MAP sensor you have A-B-C
Pin A= GROUND
Pin B= MAP SIGNAL OUTPUT
Pin C=5V
GM map

AEM 3.5/5 bar sensor:
CAR HARNESS SENSOR
Blue/Red_________________Red____________5 Volts
Brown/Black*_______________Black__________Ground
Black/Yellow_______________Green__________Output
AEM map

however this info is for a mk4 supra, im only assuming itll work for a 1jzgte?
IAT sensor

both wires on the iat are the same, since it just reads voltage.
wire 1 > pink/blue
wire 2 > brown/black
gm iat:

i believe the map is correct, im just confused on where i wire the IAT to, which wires do i jump
