well i have a 1995 civic CX and im swapping the older motor another d series NON vtec motor to a JDM D15B vtec motor... The engine is all connected and everything all lines are connected and tranny axels blah blah... I have a CX non vtec computer and i see the vtev solenoid has 3 wires were do i hook them up .. i also bought a p28 vtec ecu and im wondering wat the 1 port that has no connection is

well you will need to run a wire from the vtec solenoid (thing with 1 wire) to pin A4 on your ecu harness, one wire from the vtec oil pressure switch (thing with the 2 wire plug on the vtec solenoid) to pin D6 on your ecu harness. Then the other wire of the vtec oil pressure switch to a ground (thermostat housing ground, or a bolt on the solenoid its self is usually ok).

There shouldn't be a port that doesn't have a connection on your ecu, there should only be 3 spots for a plug and 3 plugs on your harness, they will only fit in one spot so you can't plug it in wrong.
If you have something else on your ecu, post a picture of it so we can see wtf your talking about.
