This system will not fix any mechanical issues that are causing running problems. Fix any pre-
existing problems before installation.
1. Disconnect battery negative cable.
2. Locate factory Engine Control Unit (ECU).
a.
Most ECUs are located in the passenger kick panel, or passenger floor.
b. Others are located behind the center console.
c. Newer vehicles typically mount them in the engine bay.
3. Unplug factory wiring harness plugs at ECU and unscrew fasteners holding ECU in place
to remove ECU.
5. Plug factory harness plugs into AEM Infinity Adapter Harness.
a.
Note: These will only plug in one way.
6. Mounting the AEM Infinity
a. It is recommended that the ECU be placed in an environment that does not expose it
to temperatures above 85° Celsius (185F).
b. In cases where the Infinity is to be used in place of the stock ECU, the location that
the stock ECU occupied is best.
c. On applications where the ECU is to be located in a different position than stock, the
interior of the vehicle is best.
d. The Infinity should be located in a place that allows the shortest length of wire to be
used while maintaining an environmentally sound location.
e. If this is plug-and-play, reference the Application Notes for the proper location.
7. Once the Infinity is mounted, run the USB cable to an easily accessible location away
from moisture and any sharp metal corners. Metal stamping can cut through wires very
easily. Note: The glove box is an excellent choice for the COM cable location, as it
will be used frequently.
8. Re-connect battery cable.
