I have a 98 CRV we're doing a B20 swap in. (rod knock) We picked up a JDM motor with no crank sensor and did the CKF Bypass Trick as found here. .:FFS TechNet : CKF Bypass Trick :. This CRV has a production date of 8/98, but everything I've found says a 98 Honda should be OBD2a. This CRV doesn't have the wires listed in that article for the OBD2a. Could this be an 98 OBD2b?
