okok..im in a big rush, so im hoping yall gear heads can help me out. Im doing an h22 swap into my prelude. im using an h23 wireharness. I am completely unsure what this plug is and where it goes.

The plug is closest to the knock sensor plug and the TPS sensor. Its bundled up with the TPS sensor and to the right of the knock sensor. Hopefully u can tell from th pics. This is the only plug i cant remember. PLEASE GUYS HELP ME OUT! And for anyoen that says ..its probably not going to be used, your wrong, and i only say that because the h22 wireharness has the exact same plug in the exact same place.

Come on GUYS HELP ME OUT.

 

hard to tell from the pics... is that the backside or teh distributer side? It looks like a plug for under the distributer, but I bet it's the o2 sensor plug

 

HOLY ****!!! Your the greatest...and not in a gay way either! I think your right...i think its the O2 sensor plug. Why didnt i think of that? LOL....ohh well...thats why i have you guys!! imm go double check right now.

thats the back side of the motor right under the Intake runners.

Im happy!!
