where to wire a air temp sensor on a g4 plugin ? (nissan s14)

its plug in ecu, do you wire from the air flow sensor plug or wire direct to the engine ecu. which wire becomes the input temp 2 on a plug in system ? thanks

Hi 'pcb',

If this is a Nissan Long S14, then you AFM wire will be attached to An Volt 4, on pin 27, and An Temp 2 is found on pin 55. If you carefully use a small pin/needle you could remove the wire from one and place in the other. If you've got a short header S14 then the AFM is on pin 16, and An Temp 2 is on pin 15. Hope that helps.

thanks for the reply, i think i have the short header s14, i understand i have to wire the air temp sensor to the ecu pin 15, but where did pin 15 goes to on the factory ecu or is it just a blank plug ? what about earth, where should i earth the air temp sensor ? thanks again
