Engine is a 2000 SI b16a2, im using a 96-98 EX harness. There is a plug that is on the backside of the engine that has a green wire and a black wire in it and I have no idea what it hooks to. The plug is on both the SI harness and EX harness and im trying to figure out where and what it plugs into. Any help is needed and appreciated.

Heres a few pics.

 

i cant remember exactly, but i think thats for the evap solenoid thingy.

 

i'm guessing the secondary O2 sensor. the first on is already on your header. the other one should be on the cat since the wires are reaching that far.

 

didnt think about that. Im an OBD1 balla

 

Well, the wires kinda long because the plug was broke on the EX harness so I spliced the one off the SI harness on it. And I dont think its an O2 cause it only has 2 wires and not 4, but i have no clue.

 

i just did a b20 swap into my civic a couple of days ago and i used 99-00 civic si wire harness...ill probably know where it goes to if you have a better view of the plug..like a picture of the actually plug and/or with other wires that are next to it...

 

i think it goes to a sensor on the IM

 

Looks like the sensor that plugs in down by the oil pan, I can't think of the name of it off the top of my head but I do believe that is what it is. Sorry if that didn't help but hopefully someone will see this and fill in the blank I left...Good luck

The plug I'm talking about is routed over the alternator and plugs in right below it.

oh yeah, if its OBD2 its prolly the CKF sensor

 

dont worry about it... when i did my b16a2 swap in my 96 hatch and used a 96-98 harness i had about 3-4 extra plugs left over.. it ran perfect without any codes..

it sort of looks like the IAT sensor plug on the IM.

 

CKF dont need it cause your OBD1

It has the same plug as the IAC but that is already plugged in. Ill take some more pictures tonight and post them.

What is the CKF sensor?

Quick thought, could this possibly plug into a evap purge solenoid?

 

intake air temp sensor. what color ate the wires? red/yellow and green/blue?

 

One wire is green and the other is black

 

I think it may go to #9 in this pic. Its missing on my manifold and thats why the plug is just hanging. What do yall think? And what is it?

that was my guess as a matter of fact, im going to go check on the vic right now.

 

my evap purge solenoid on an obd1 civic ex had 1 red and 1 yellow wire.

 

has that harness been modified? It probably goes up to the purge solenoid but its hard to tell. Is that the only thing you dont have plugged in? Wiring really isnt that sensitive. you can throw the engine in and turn on the ignition. if you have the wiring wrong you will get a cel but then it will tell you whats wrong and then you can make adjustments from there. nothing would be damamged.

 

I am pretty sure it goes to you steering rack for your power steering. I broke the same wire when I pulled my motor. didn't even know it was there.

Hes exactly right I just checked. Its for the power steering pressure switch.

 

That is the only plug that isnt hoked up, I just wanted to figure out exactly what it was for before I drop it in the car. So its the power sterring preasure switch.

Thanks for the help fellas

 

no problem.
