There's a wire that has the RPM signal from the distributor in one of the blocked off plugs on the driver side of the engine bay by the shock tower. Those plugs are normally used for testing but, like tony_2018 said, you don't have a distributor RPM wire routed into the cabin with an OBD2B wire harness, but IIRC they still have the blue test wire over there.
