H23 to H22a4 swap ?'n (oil pressure swith)

Ok I have a 92 Si prelude that previouslly had and H23a1,and I'm currentlly in the process of swaping in my H22a4 its about 60-70% done just had a question regarding the oil Pressure switch that goes on top of the oil filter I Mean I See the Threads in the block were sensor would go but if I recall correctlly the H23 didn't have one but I read somewere online during my searching that the sensor is needed and has too be wire up

Now my ?'n is do I need this sensor and how those it get wired up?

Yes you NEED an oil pressure sensor!! Both H23 and 22 have one, just take one off your 23 and use it on the 22.


I think you might be thinking of the KNOCK sensor which is also above the oil filter, a bit higher, but all H's have a KS, while F's don't have them.

Oops I'm confusing the H and F's myself. Sry!

on the H23, the KS is on TOP of the oil filter, and has 2 wires going to it. The OP switch is below the filter, with only one wire and a rubber boot over it.

Ok soo yea,I took the OP sensor that was coverd with the rubber boot off my H23 and swaped it over too the H22a4,which should mean that I dnt need anything in the empty thread above the oil filter??

It was there, trust me

Just use the engine harness that goes to that engine (and ECU), and you'll be good
