There are two AEM 4 Channel Coil Drivers included with this kit. Each must be connected to the adapter
harness with one 4P and one 5P connector. Ensure that the 4P and 5P connectors marked “Coil 1”
connect to opposite ends of the same 4 Channel Coil Driver. Similarly, the 4P and 5P connectors
marked “Coil 2” should also be connected to opposite ends of the second AEM 4 Channel Coil Driver.
The grey Deutsch 2P DTM “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 requiring this connector.
The grey Deutsch 2P DTM “Fuel Pump” connector is used for an optional user modification discussed in
the "Fuel Pump Modification" section allowing the Infinity EMS to control the Ford Racing harness Fuel
Pump relay.
The grey Deutsch 12P DTM “AUX” connector 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 molded into the connector, as shown.
WIDEBAND/UEGO SENSOR ADAPTER HARNESS
Included with the AEM Infinity EMS PNP adapter harness kit are two LSU4.9 to LSU4.2 adapter
harnesses. These are used to make the connection between the Ford Racing Control Pack harness and
LSU4.2 Wideband 02 sensors (AEM P/N 30-2001).
NOTE: The AEM Infinity EMS is compatible ONLY with Bosch LSU4.2 sensors. These adapters are
supplied to ease installation and minimize the need to modify wiring. An AEM Infinity EMS should never
be plugged in and turned on with Bosch LSU4.9 (original Ford Coyote sensors) connected. It is
imperative that the original Ford O2 sensors are unplugged from the wiring harness before connecting the
AEM Infinity EMS.
