I did a f20b swap in my 95 prelude and used the stock wiring harness. The motor is in and running good. I am using a chipped p28. the f20b doesnt have a oil pressure switch so i ran A4 which is vtec solenoid and D6 which is vtec prewssureon switch together to take away the check engine light for the vtec pressure switch. So then i have no check engine light and i ran it vtec kick in and then quit and the check engine light came on and was cel 21, which is vtec solenoid. I went through the wires and changed them a ciouple times and went back out and did the same thing over and over again. I would clear the ecu and it would keep repeating. everytime you clear the ecu it kicks on then goes off again an come back with the check engine light. Any thoughts on how i can get vtec to stay??? Would appeciate the help, thanks
