Putting a Gsr into a 98 civic 2dr

[CTinTEG]

Need help. The wiring harness that came with the engine was completely wrong. Can I use the stock ex harness that came with the car? And how can I be sure that the place sent me an obd2 Gsr. Its a b18c. I ordered a obd2 motor. Please reply asap or anyone please call me at 203-260-3796.

yes you can use the ex harness, you "may" have to extend the vtec wire, not sure, but im possitive you can use the ex, or even better the si harness

if its obd2 civic you need to use the car harness. ex or si will work as stated above. you do not need to extend the wires they will reach if you pull back the tape a little bit, and make sure you get the right harness! 96-98 = obd2a 99-00 = obd2b

use the car harness that you had in there car. and if they sent you a obd2 motor the injectors will plug right in if the motor is obd1 the injectors will be different.

Someone please call me on this. I have a few plugs that don't go anywhere And a can under the intake manifold with a sensor that idk where to plug in. Someone please call me asap about this or give me a number of someone I can call.

Also there is a fifth plug on the ex harness where the injectors are. What does that plug too...? And there is an extra plug on the harness that used to plug into a connector that came out of the block on the ex motor. Where does that go? The fifth plug where the injectors are plugged into some sort of vacuum sensor above the fuel rail on the ex motor. That's not on the Gsr unless that's the can thing under the Gsr intake manifold. Someone please help.

that would be for your purge solenoid i believe, you pretty much dont need it,
and there might be another plug that you dont know what is for, its suppose to be for your intake manifold, but you dont need it for the gsr, the gsr already has taht sensor in the intake, i think its the air temp sensor, correct me if im wrong

How do I know if I need obd2 a or b? I don't know the exact year of the b18c I got. Just know it's obd2

i believe there should be a 4 digit code on the head near the headers the first 2 digits are the year correct me if im wrong
