Locations For The Status LED
Things to remember when positioning the Status LED:
It should be visible from both sides and the rear of the vehicle, if possible.
It needs at least 1/2-inch clearance to the rear.
It is easiest to remove a small panel, such as a switch blank or a dash bezel, before drilling a 9/32-
inch hole.
Use quick-disconnects near the LED wires if the panel is removable. This lets mechanics or other in-
stallers remove the panel without cutting the wires.
LOCATIONS FOR THE IMMOBILISER RELAY - starter kill relay
If Immobiliser relay or its connections are immediately visible upon removal of the under-dash panel, they
easily can be bypassed. Always make the relay and its connections difficult to discern from the factory wir-
ing! Exposed yellow butt connectors do not look like factory parts, and will not fool anyone! For this reason,
routing the Immobiliser relay 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 or logic probe (computer safe test light) to find these wires! Use
a digital multimeter 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. If the fuse also will
be powering other circuits, such as door locks, a power window module, headlight control system, etc.,
fuse accordingly.
Finding The 12v Switched Ignition Wire - ON
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 current available to
the starter motor.
How to find (+) 12v ignition with your multimter:
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 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.
