Analog Inputs 5 - 8
These inputs have a jumper-selectable 5V pull-up resistor and are suitable for a variety of sensors, either sensors
that are being added to a vehicle or pre-existing (or OEM) sensors. Pre-existing/OEM sensors are presumed to be
already connected to a factory ECU or logging device which will require different wiring and jumper setting
considerations. Please refer to the table below for connection examples.

CAN Output
The measured voltage and resistance will be output via CAN and will have to be scaled to the desired units (e.g.
temperature, pressure, percentage, etc) in the receiving device. A thermistor's voltage/resistance varies non-linearly
with temperature and thus the receiving device will likely require a look-up table to properly log or display
temperature. Most non-temperature sensors require a simpler linear scaling. The AEM CD series of dashes have
both of these capabilities; please refer to the appropriate documentation.
Note: The resistance value output via CAN is not valid when the pull-up jumper is in the "100kOhm" position. Please
refer to the voltage output.
Analog Inputs 9 - 12
These inputs have a 2200 Ohm 5V pull-up resistor and are suitable for two-wire thermistor temperature sensors. It is
not recommended to connect these inputs to pre-existing/OEM sensors that are already connected to a factory ECU
or logging device. Please refer to the table below for connection examples.
