vtec swap help
i just did a swap in a 93 cx. i put in a jdm d15b and im not sure about the vtec wiring. i have hooked up the vtec solenoid but im not shure about the vtec pressure switch. the ecu (p28) is throwing a 22 code which is the vtec pressure switch prob. because its not hooked up. basicaly i just need know where the vtec pressure switch is so i can hook it up. the solenoid only has one wire and thats going to the ecu.

Hmm....There should be a second wire....The big circular thing is the Vtec solenoid, and under it is the pressure switch

Re: vtec swap help
well.. you may have a small problem. Some d15b's didnt come with vtec pressure switches. So youll have to wire one up seperately. Heres a pic of what a normal vtec selenoid and pressure switch look like....
Now the next pic. is what some d15b's look like without the pressure switch. Now you can install and wire up the pressure switch where the red arrow is pointing to the bolt. Remove that bolt and install a pressure switch there. Youll then have to run a wire to pinout D6 on your ecu. I have included a diagram for you.
here is the wiring diagram
HOPE THIS HELPS!! GOOD LUCK
