INFINITY ADAPTER HARNESS
Included with the 2001 – 2005 Honda K Series kit is an adapter harness. This is used to make the
connection between the AEM Infinity EMS and the Honda wiring harness plug and play. This is depicted
below with the 80-pin connector and the Honda header. There are also a few other integrated connectors
within this harness described below.
The gray Deutsch 6P DTM “LAMBDA” connector is for connecting a UEGO wideband Bosch LSU4.2
sensor (AEM 30-2001). The UEGO extension harness (AEM 30-3600) mates the adapter harness to the
sensor.
The gray Deutsch 4P DTM connector is used for “AEMNET”. 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 black Delphi 2-pin “FLASH” connector is used for secondary hardware flashing. The included shunt
connector jumps the 2 wires together. Once initially flashed, the EMS is normally upgraded in the
software, not using this connector.
The red flying lead labeled “Battery+” is to be connected to a permanent +12V source. This source
should be independent of the ignition switch. The OEM Honda ECU does not have a permanent +12V
power pin, so this must be sourced separate from the OEM connector and should be protected with a 5A
fuse.
