so i finally got the right ECU for my civic, got it started and checked the CEL codes pulling a 10 IAT sensor, understand that one because it doesnt have one, i think, but im not 100% sure where it is. second code and the one i really have no clue on code 41 H025 heater according to my book and 41 Primary oxygen sensor heater according to the DIY, so i figured that would be the same...
ok so what is the primary oxygen sensor heater and where is it located?

thanks for the help

The IAT is mounted to the intake manifold on most Hondas and on some it's in the intake tube just before the throttle body.

The O2 sensor heater is integral to the sensor.

ok so i ordered my IAT sensor, and bought a O2 sensor.
i installed the IAT (there wasnt one on the car) and its still throwing the code 10 and I cant figure this one out.

also got the O2 sensor...they gave me a 4 wire O2 and im not sure thats what i need for my car, but i dont know because there was no O2 sesnor on the car and i have no clue where the plug is to install it

any help is greatly apprecieated

ok so i fixed the IAT problem...i had it plugged into the wrong one. found the right plug and switched it, but i dont have the hole in the intake manifold to put the sensor...not sure if the intake is the right one or not. did the JDM B18B's not have the IAT sensor switch location on the manifold?

still cant find the O2 sensor plug and still not sure if its supposed to be 4 wire or not?

will a USDM B18B1 intake manifold fit on aJDM B18B?

and will i be able to use a USDM automatic transmission wiring harness on a JDM engine and S80 tranny?

i sourced a USDM automatic 95 integra at a junkyard and just was just wondering if i could pull these parts off of it...

i hope someone can help me
