When compared to the OEM EMS on the left, the AEM Infinity is tiny. It is ruggedized for competition use and has USB ports for easy data access.
What makes the installation a snap is this awesome plug and play harness that AEM provides. Not having proper wiring is the downfall for many grassroots racing efforts and having a decent plug and play wiring solution is wonderful.
If you don't have much imagination, the blue connector on the harness plugs into the Infinity's main OEM quality locking connector.
Plugs in just like so,
The other end of the harness has an OEM female connector just like the stock EMS that the factory harness plugs into.
The other connectors plug directly into the factory plugs. There is an auxiliary connector for data logging, traction control, map selector, etc.
