Finding The Wires You Need - Clifford Responder LE 3.3X Installation Manual

Finding the wires you need

Now that you have decided where each component will be located, you are ready
to find the wires in the car that the security system connects to.
Important! Do not use a 12V test light or logic probe (computer safe test light)
to find these wires! Use a digital multi meter for all testing.
Obtaining constant 12V
We recommend two possible sources for 12V constant: the (+) terminal of the
battery, or the constant supply to the ignition switch. Always install a fuse within
12 inches of this connection. The fuse will also be powering other circuits such
as door locks and interface modules, so fuse accordingly.
Important! Do not remove the fuse holder on the red wire. It ensures that the
control module has its own fuse, of the proper value, regardless of how many ac-
cessories are added to the main power feed.
12V switched ignition wire
The ignition wire is powered when the key is in the run or start position. This is
because the ignition wire powers the ignition system (spark plugs, coil) as well
as the fuel delivery system (fuel pump, fuel injection computer). Accessory wires
lose power when the key is in the start position to make more current available to
the starter motor.
