30-0311 - OBD-II
The 12V power available at your vehicle's OBD2 port is a permanent "always on" 12V, no key switched power is available
at this port. The AEM X-Series OBD2 Gauge uses a specific algorithm to detect when the key is on and the engine is
started to boot up or shut down, conserving power. The engine must be running for the gauge to remain on and booted up.
NOTE: It is advised to unplug the gauge from the OBD port if the vehicle is to be stored for long periods of time
to avoid excess drain on the battery.
What pins are used in the connector?
To populate optional extras, use JST P/N SPUD-001T-P0.5 terminals for 22-26 AWG wire.
