Infinity Adapter Harness
The basis of the VW 1.8T Infinity kit is the adapter harness that mates the Infinity ECU with the cars factory wiring
harness. This adapter allows for seamless integration of the Infinity EMS onto your vehicle.
AEMNet is an open architecture based on CAN 2.0 which provides the ability for multiple enabled devices, such as
dashboards, data loggers, etc. to easily communicate with one another through two twisted cables (CAN+/CAN-).
The 2 pin Flash Enable connector is used as a secondary hardware flashing option by jumping the two wires
together using the included shunt connector. Note: Flashing will normally be performed in the software not using
this connector.
Integrated in the 1.8T adapter harness is an “auxiliary” connector. This is a Deutsch DTM 12P connector and is
used to adapt many common ancillary inputs and outputs easily. Included in the kit are a DTM 12P mating
connector, 12 DTM terminals, and a DTM 12P wedgelock. If used, these components will need to be terminated by
the installer or end user with 16-22awg wire (not included). Note: the pin numbering is based on the numbers
molded into the connector.
