On a 1997 Honda Accord EX, the oxygen sensor wire is typically connected to the vehicle's wiring harness, which runs along the engine bay. The oxygen sensor itself is located in the exhaust system, usually before the catalytic converter. The connector for the oxygen sensor is often found near the engine, close to the intake manifold or along the firewall, depending on the specific sensor being referenced (upstream or downstream). Always refer to a repair manual for precise locations and wiring diagrams.
