2 97N437.597 Do not disconnect the battery if the vehicle has an antitheft-coded radio. If equipped with an air bag, avoid disconnecting the battery if possible. IMPORTANT: Many airbag systems will display a diagnostic code through their warning light after they lose power. Disconnecting the battery requires this code to be erased, a procedure that can require a trip to the dealer. Before beginning the installation: • Check with the customer on Status LED location. • Remove the domelight fuse. This prevents accidentally draining the battery. • Roll down a window to avoid being locked out of the car. After the install: • Test all functions. The "Using Your System" section of the Owner's Guide is very helpful when testing. • When testing, don’t forget that this system is equipped with Nuisance Prevention® Circuitry. NPC™ can bypass trigger zones, making them appear to stop working.

3 97N437.597 Step One: Deciding on Component Locations Siren Some things to remember when mounting the siren: • Keep it away from heat sources. Radiators, exhaust manifolds, turbochargers, and heat shields are all things to avoid. • Mount it where a thief cannot easily disconnect it, whether the hood is open or shut. Both the siren and its wires should be difficult to find. This usually involves disguising the wire to look like a factory harness. • We recommend against grounding the siren to its mounting screws. Instead, we recommend running both the red and black wires into the passenger compartment and grounding to one common point for all devices. After all, both wires are the same length and come already bonded together. Whenever possible, conceal your wires in the factory harnesses or in the same style loom as the factory. • When possible, put the siren on the same side of the vehicle as the control module, where its wires will reach the control module’s wires without extending them. Always run the wires through the center of a grommet, never through bare metal! • Point the siren down so water does not collect in it. Control Module Never put the control module in the engine compartment! The first step in hot-wiring a vehicle is removing the driver's side underdash panel to access the starter and ignition wires. If the control module is placed just behind the driver's side dash it can easily be disconnected. When locating the control module, try to find a secure location that will not require you to extend the harnesses’ wires (they are 1.5 meters long). Keep it away from the heater core (or any other heat sources) and any obvious leaks. The higher the control module is in the vehicle, the better the transmitter range will be. If you put the control module under a seat or inside a metal dashboard, range will suffer, and you may wish to add a 542T Range Extending Antenna (available separately). Some good control module locations: Above the glove box, inside the center console, above the underdash fuse box, above the radio, etc.

4 97N437.597 Stinger® Doubleguard® Shock Sensor Never put the Stinger® in the engine compartment! Find a spot close to the control module so that the wires do not need to be extended. Keep it away from the heater core (or any other heat sources) and any obvious leaks. How the Stinger is mounted is the most important factor in its performance. We recommend two mounting methods: Using double-sided tape or hook-and-loop fastener to mount to a trim panel or an air duct, or wire-tying to a wire harness. If mounting the sensor where it cannot be easily reached for adjustment, hook-and-loop fastening tape (such as Velcro) is recommended for ease of removal for future adjustments. NOTE: In many vehicles, tying the sensor to a steering column or screwing it to metal will result in poor sensitivity, especially on the rear of the vehicle. Valet® Program Switch Ensure that the location you pick for the switch has sufficient clearance to the rear. The switch should be well hidden. It should be placed so passengers or stored items (such as in a glove box or center console) cannot accidentally hit it. The switch fits in a 9/32" hole. This system has Remote Valet®. The user can enter and exit Valet® Mode without having to reach the Valet®/program switch. DEI® introduced this feature so that switch location was less critical in day-to-day use. As long as the Valet®/program switch can be reached to disarm without a transmitter, easy access is not important. IMPORTANT! When the vehicle is delivered, please show the user where the switches are located and how to disarm the system with it. Status LED Things to remember when positioning the Status LED: • It should be visible from both sides and the rear of the vehicle, if posible. • It needs at least 1/2" clearance to the rear. • It is easiest to use a small removable panel, such as a switch blank or a dash bezel. Remove it before drilling your 9/32" hole. • Use quick-disconnects near the LED wires if the panel is removable. This lets mechanics or other installers remove the panel without cutting the wires.

5 97N437.597 Optional Starter Kill Relay If Starter Kill Relay or its 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. Step 2: 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! 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. 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. 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). Accessory 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.
