intake air temp wiring..

[CRXer]

ok thanks... oh but looking at the connector on the intake the 2 pins are top to bottom, top pin ground or bottom pin??? sorry i should have explained myself more.... and what about that purge just leave it????

doesnt matter which way iat plug is wired,its a thermistor(temp sensitive resistor) so polarity dont matter.

the other spare plug u found is prob the purge plug,see if u can see what pin the red wire goes to at ecu end to confirm.

not sure what obd2 will do with lack of purge solenoid hooked up,i assume it will CEL,but ecuman will know.

you should really do a continuity test back to the ECU to ensure you have the correct wire before connecting it. you dont want to blow the ECU

youd prob do well to follow this advice,as i dont know what is going on with your conversion harness/whatever back at ecu
