Hi everyone. I've been running without a catalytic converter for a while now. I've also been running without the little lightbulb for the check engine light cause running without a cat would cause it to come on. I remember seeing something once that goes wired into the o2 sensor to trick the cel into not lighting up, but I've searched and can't find it anymore. I was wondering if anyone on here knows how to make the cel not turn on when running without a cat?

That was great. Thanks.
