No the CX is not wired for VTEC, only the Si and VX have VTEC wiring in the factory harness. Don't use a GSR harness use the stock harness for your car it will make things easier. Basically everything should plug into your factory harness assuming you have an OBD1 GSR engine, except for the VTEC components and the IAB for the intake manifold. I only have the pinouts for the OBD0 ECU on my computer, but I'm sure you can find them by searching here or Google.
