Starter Kill Relay
If the Starter Kill Relay or it’s connections are immediately visible upon removal of the underdash 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.
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! All testing described in this manual is
described using a digital multimeter.
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.
IMPORTANT! Do not remove the fuse holder on the red (H1/11) wire. It ensures that the control module
has it’s own fuse, of the proper value, regardless of how many accessories are added to the main power
feed.
Finding the 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). Ac-
cessory wires, on the other hand, lose power when the key is in the start position to make more current available
to the starter motor.
How to find (+)12V ignition with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the ignition wire.The steering column
harness or ignition switch harness is an excellent place to find this wire.
4. Turn the ignition key switch to the run position. If your meter reads (+)12V,
go to the next step. If it doesn’t, probe another wire.
5. Now turn the key to the start position. The meter display should stay
steady, not dropping by more than a few tenths of a volt. If it drops close to or
all the way to zero, go back to step 3. If it stays steady at (+)12V, you have
found an ignition wire.
