USB & CAN Connector
The Infinity ECU includes high quality weatherproof bulkhead USB and CAN communications.
Plug one end of a standard USB extension cable (included) into the ECU connector and the
other end into an open USB port on the PC. Communication is possible only when the ECU is
powered up.
Auxiliary Connector
All Infinity PnP Harnesses include a 12pin "auxiliary" Deutsch connector. This male pinned
connector is used to adapt the most common ancillary inputs and outputs easily.
AEM carries the mating connector (sold separately) in a universal format, where all 12 pins are
stuffed with flying leads (shown below). However, depending on the PnP application many of the
I/Os found on this aux connector may already be used in the factory engine harness. Furthermore,
some of these I/Os may be used for other vehicle functions. In these cases, the PnP harness may
not have all 12 pins stuffed. See the specific Application Notes that came with for more
information
