Ive got a built gsr turbo and i went to get tuned the other night come to find out my iat sensor is bad or ive got a wiring issue. Its in a 99 gsr, therefore obd2b and the complete engine setup, wiring harness and everything is all obd1. Someone tell me please no guessing i need to know the exact color of the two wires for an obd1 iat.

 

What year is the OBD1 out of please.

 

You can't always trace just by wiring color. If the factory runs out of a certain color there not gonna stop production. They will put in whatever they can. Always trace by pin locations. Katman has a good site where he has all the pin outs for the ecu. You can check your sensor too by getting it cold and put a meter on the terminals and check the resistance if it goes up as it gets cold then its working.
