Voltage, Boosted Harness and PCM Bypass
Unless otherwise quoted or selected, plug-and-play units use the OEM voltage setting. On PCM- or ECU-controlled vehicles, the vehicle computer normally controls charging voltage.
Boosted harness options: The options available on this listing are 15.3V with one diode or 15.5V with two diodes. The selected diode arrives installed in the harness.
PCM/ECU bypass: A bypass changes charging control from the vehicle computer and sets charging voltage to 14.8V. A bypass is required when using a boosted harness. In most cases, the battery warning light will remain illuminated after a bypass.
