https://imgur.com/a/m2T5wHi, I've got a cb7 with a F20b in it. Previous owner did the motor swap but did not install the ecu or hook up the vtec. I'm trying to find the proper way to hook up my vtec. I've read about the jdm motors do not have the vtec oil pressure switch and needs to obtained somehow and then wired. Is this correct and if so, can I have more details on what I actually need to do. If it's incorrect, please assist me with the correct information. I've got a picture of my engine from the vtec solenoid and also a couple pictures of my ecu. Thanks in advance.

 

I put a f20b in my cd7 many years ago. I will try to help as best I can however I forget a lot of the details. I remember that the distributer was hard to wire up and required looking at the wiring diagram and wiring up according to that.

Also I had to switch two pins at the ECU, I can't remember what the two were but hopefully you can google it and find out what two they are to make the vtec work.
