3 Hardware
3.1 Connecting Power
Option 1: Using the Cigarette Lighter Power
This option is ideal if your cigarette lighter power is only ON when your ignition key is turned. In some
vehicles, your cigarette lighter power is always ON. Leaving your DM-100 OBDII unit always powered on,
will drain your vehicle’s battery quickly. If this is the case for your vehicle, we recommend option 2.
Plug the 2.1mm power plug to the DM-100 OBDII main control box where indicated “POWER.” Plug the
cigarette lighter adapter connector into your cigarette lighter power plug in your vehicle.
Option 2: Hardwire your power connection
CAUTION! CONNECTING THE DM-100 OBDII IN REVERSE POLARITY
WILL DAMAGE THE UNIT! CHECK CONNECTIONS BEFORE POWERING
ON.
