The OBDII Pass-Through Splitter allows two products to be simultaneously plugged into the OBDII port such as an Edge monitor unit, and another product, including, but not limited to, power running boards or other potential OBDII powered products. This new OBDII splitter is fully populated with a 16-pin pass-through, pinned connector. Products may vary on what can be running at the same time. Not recommend being used with two monitors or tuners plugged in at the same time.
This is perfect for trucks running AMP steps with gauge monitors or other similar accessories that both require OBDII access.
Please note that some modern trucks do not allow two full time communication devices. For example, you can run a CTS3 gauge system and AMP steps as the AMPS are intermittent communication, but not a CTS3 and a Carli E-Venture system since both are constant communication devices.
