The Duo 9-Pin pass through cable is recommended for vehicle installations where a type I (black) or type II (green) 9-pin port is present. It connects directly to the vehicle diagnostic port utilizing the male connector and allows an additional cable to be attached using the female connector. The female connector can also act as an open source for plugging in service tools as the male connector will occupy the vehicle’s standard diagnostic port. Please consult with a Pana-Pacific sales representative for assistance determining if the vehicle is equipped with this configuration. This cable is included in the Trimble Duo 9-Pin Kit (M-010-0683).
