How is the Ignition Interlock Device connected?
An Ignition Interlock Device (IID) is larger than a cell phone
and is wired to your vehicle's ignition. A standard Igntion
Interlock has four main cables. The 12 Volt, Igntion Hot, Starter
and Ground in order ot operate correctly. You have to have direct
12 volt, and solid ground, then you interrupt the starter wire and
connect the interlock starter kill to that, and last is the
ignition run, so when you turn the key it activates the
Interlock.
How it installs varies from car to car, but basically it
disables your key from reaching the engine. The device prevents the
engine from being started if the breath alcohol concentration is
too high.
It needs to be installed by a state certified installer along
with a lot of official paper work, so it is not a do it yourself
thing.
More importantly, criminal sanctions exist for circumventing or
tampering with an Ignition Interlock Device.
In Arizona, QuickStart Ignition Interlock AZ is one.
