does anyone have any wiring diagrams that might help my mechanic shave some costly hours off a h23 to h22 conversion???
does the dash need to be removed in this example?

hours? https://honda-tech.com/zerothread?id=549372 look there that has the pin outs. all you going to need to wire is the vtec solinoid , oil press sensor, and i think the IAC which is the secondary butterflys in the intake mani.

im having a brain fart right now, i don't know if the secondary buterflys in the intake mani is IAC or IAB, i don't remember but its a secondary runner that is opened up at a certian rpm when the car reaches the predetermined RPM because of the higher demand for sir when vtec engages

 

Well i'm actually in the middle of swapping out an H23A1 out for a H22A4 true JDM. The only things that you'll have to change is some harnesses not sure which ones yet and if the engines 97 or newer you'll need that ecu because the engines have a CPS sensor and you'll need the 5th gen ECU to run the motor, also you'll need to swap your intake manifold in since the 4th gens have cruise control vacumme lines running into it and the 5th gens dont.

Other than that pretty straigh forward.
