I'd like to cut my air filter restriction gauge completely out of the engine bay (just to keep things tidy) but need to know if it's "safe" to do so first. I disconnected the gauge and the engine started/ran fine without the "change your air filter" idiot light on the dash lighting up. At the harness-end of the plug, I measured ~13.2 volts across the terminals but not I'm curious--is it alright just to chop the wiring off, seal the ends up, and press on or does the presence of a voltage across the plug terminals mean something I don't understand?
