In this picture is a Ls b18a1 block....that green sensor to my knowledge of searching should be a Engine Oil Temp Switch....ok my question is I'm doing an h2b swap in my db1 and was wondering where is this sensor located on a h22a4 base model...this is the last sensor I have to wire up into my harness thanks!! The plug is on the harness but don't know where it plugs to!!! Please help!!

 

The H22 has no oil temp switch, just coolant temp and they are all up on the water passage at the tranny side of the head, and thermostat housing and water neck.

The closest thing with a plug like that on that section of the H22 harness will be the power steering sensor down there, if the 5th gen had that like the 4th gens do.

 

that looks like knock sensor h22a4 should be in the same spot

 

Thanks alot for clarifying that for me!!! I was stuck for ah few hours thinking n searching where this plug goes to -_-".....I guess ill just eliminate it then...

 

Nope my knock sensor is up top close to the cylinder head..

 

The Knock sensor goes right above the oil cooler like in this picture, the one in the picture is broke off:
