If starter kill relay or its connections are immediately visible upon removal of the under-dash panel, they can
easily be bypassed. Always make the relay and its connections difficult to discern from the factory wiring!
Exposed yellow butt connectors do not look like factory parts, and will not fool anyone! For this reason, routing
the starter kill wires away from the steering column is recommended.
finding the wires you need
Now that you have decided where each component will be located, you’re going to find the wires in the car that
the security system will be connected to.
IMPORTANT! Do not use a 12V test light to find these wires! Use a digital multimeter for all testing.
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. If the fuse also will be powering
other circuits, such as door locks, a power window module, a Nite-Lite
®
headlight control system, etc., 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 accessories are added to the main
power feed.
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.
