That's true for the RCEXL and some others with the braid/shielding wire connected to a metal spark plug cap. The CH Ignitions units with the rubber spark plug cap/connectors need to be grounded. In fact, repeatedly turning the engine over with the ignition on but without the plug being grounded can ruin the sensor.
