Switched Ignition 12V
The Switched Ignition flying lead (PNK-WHT) must be connected to the output on the ignition switch that supplies 12V
when the switch is in the Start and Run position. The ignition switch output should be isolated, meaning that it is dedicated
to the PNK-WHT wire, and should NOT supply switched ignition power to any other device.
Perm 12V
The Perm 12V/Fused 5A PNK flying lead can be used to power the ignition switch if the switch does not already have a
12V source wired to it.
Tacho Output
The Tacho Output (20AWG ORN-WHT) transmits a 0-12V pulse signal. The Tacho Output can be configured in the
Infinity Tuner Wizard to transmit the desired pulses per engine revolution in order to match the installed tachometer.
INFINITY CONNECTORS
The AEM Infinity EMS uses the MX123 Sealed Connection System from Molex.
Refer to the 10-7100 for EMS 30-7100 Infinity Quick Start Guide for details on
