Why would you need a whole wiring harness? You're swapping in an OBD1 F22 for an OBD1 F22. All you'll need to so is add wiring for VTEC. And I don't know where you're looking for ECUs, but check the "For Sale" section down at the bottom of the main page here, and check Craigslist, E-Bay and any local tuner forums for your area. These aren't that hard to find...
