i have a Jap b16a1 and i have been running my car with out the O2's sensors and its been a few months and my i really dont want to ash out the valves and do damage to the engine. But i was told that Stock DX models didnt come with o2 sensors that would fit the b16 connectors. do i have to change the wiring harness, what do i look for? what do i need.? and if i were to replace the entire harness would it fit the stock ECM i already have for it? and would the the other connections be the same for everyhing else. injectors, distrubitor. if any one could help please! i want to hook up my o2's
