I have the K-tuned IAT adapter, it allows the use of a K or obd2 B-series IAT sensor. I'm using the stock RSX-S harness as I've had to add some sensors/INJ plugs, that being said the IAT plug is missing. Finding an RSX/TSX etc that isn't picked clean is next to impossible here, my question is, is the plug of the OBD2 b-series IAT the same as the K series one?, can I use the plug from an obd2 B engine on my RSX harness, I don't have a 90's civic/integra to go look.

Hoping someone can run out to the garage and snap a pick of their obd2 "B" plug, i'd like to hit the junkyard on my one free day.

Thanks.

 

Google images isn't turning up anything, Will the obd2 b series plug work on the RSX harness, they're both 2 wires. Or even a pin out?

 

You're asking if you can solder a B-Series OBD2B IAT plug onto your RSX Engine Harness and plug it into a B-series IAT, right?

The only thing I can think that would be different between the IATs that, maybe, your ECU would care about would be if there are different readings at different temperatures. I'd pull the FSMs off HondaHookup and compare the test procedures.

You could also check in the Hybrid subform (hybrind as in car x with engine y not battery) or the K subform. They may know a little more.

 

Yes, k-tuned says you can use an obd2 B series sensor with the k-series plug(no modification req). So i'm assuming/hoping that means the B series plug is the same, as the sensors are the same(according to them). I have K-Pro so that'll help heavily in knowing if it's reading right, I was just hoping for a pic from someone of the obd2 plug.

The only issue comes from, are the plugs them selves the same. Is the obd2 B IAT plug a 2 wire? if so it should work no issues.

 

I am currently unable to run out to my car and take a photo, but the thread I posted a link to has some good pictures of the obd2 IAT plug and yes it is two wire plug. The evap canister plug if I remember correctly is the same as the IAT sensor plug, but the purge solenoid plug is slightly different, but can still work if you shave part of the sensor a bit.

yup, there are 2 plugs that are the same.
