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 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
WARNING! CONNECTING THE DM-100 IN REVERSE POLARITY WILL
DAMAGE THE UNIT! CHECK CONNECTIONS BEFORE POWERING ON.
DAMAGE TO THE DM-100 WILL VOID YOUR WARRANTY.
The DM-100 accepts 12-18V DC for power. Connect the negative wire (black) to your vehicle’s ground.
This is usually the negative terminal of your automobile’s battery. Connect the positive wire (red) to your
vehicle’s ignition power. This power is only supplied when your key is turned passed a specific position and
is off when your key is removed. Your power connection must be capable of supplying at least 1 amp of
current. A 5 Amp fuse is recommended for safety. Plug the 2.1mm power plug to the DM-100 main control
box where indicated ‘POWER.’
