i have an 90 hatchback with a d16y8 swap in it. but the IAT sensor isnt plugged because there is no sensor for it. i was told that the sensor is on the intake tube.? so ill need to find a 96+ civic ex intake tube? anyone have one for sale?? where will i hook up the sensor to? do i have to weld?

 

you dont need that sensor unless you converted your 90' civic to OBD2.....if it's still OBD1, then just plug the hole or wrap it with electrical tape

 

i think it is obd0 because i am using 89 si ecu.
