Car alarms are a basic part of vehicle ownership. One of the best manufacturers of car alarms is Viper--its Viper 5000 may be one of the greatest car alarms ever designed. The Viper system can be programmed to do anything from opening the door and lighting the dome lights, all the way up to turning off the starter if your car is reported stolen. The Viper 5000 can also be a little intimidating to look at if you are a novice at installing alarms. Here is how to install the alarm.
Identify the primary wiring harness--it will have 12 wires, labeled as H1/1 through H1/12. The colors of the wires are red/white, red, brown, yellow, black, violet, blue, green, black/white, white/blue, white and orange. Locate this harness and get ready to wire it into your car's electrical system.
Locate the H1/1 wire on the primary wiring harness. This is the red-and-white wire. Connect the wire to the trunk release button on your automobile. You should be able to loosen a screw on the backside of the trunk release button, allowing you to insert the wire along with the original trunk release wire, before tightening the screw back down. This allows your Viper 5000 car alarm remote to open the trunk of your car.
Find the H1/2 wire, which is colored red. This wire is the primary input for the Viper 5000 car alarm. Remove the fuse from the wire before connecting. There are two options for where to connect the red wire. You can connect the wire directly to the positive power terminal on your car battery, or you can open the car ignition and splice the wire into the wire that supplies 12V power to the ignition. To do this, use your wire strippers to remove a small amount of insulation from the ignition wire. Splice in the red wire from the Viper 5000 and then wrap the connection with electrical tape.
Connect the brown wire on the Viper 5000 car alarm, identified as H1/3. Connect the brown wire directly to the red wire on the Avenger siren and mount the siren under the hood of your car. Connect the black wire of the siren directly to a metal section on the car body. The brown wire supplies power to the siren whenever the alarm determine it is needed. The siren's black wire serves as a ground for the current.
Take the yellow H1/4 wire on the primary wiring harness of your Viper 5000 car alarm. Connect the yellow wire directly to the positive (+) 12V ignition wire. If you chose to connect the red H1/2 wire to the ignition, you can connect this one at the same time. It is important for the yellow wire to have a full 12 volts of electricity when the car's key is turned to the on position. Check the 12V ignition wire carefully to make sure there are no nicks, cuts or other problems that could cause the current to short.
Prepare to install the ground for the Viper 5000 car alarm by looking under the hood or body of the car for a bolt. Find a factory-installed boat that does not have any other ground wires leading to it. Remove the bolt from the bolt hole. If there is any paint on the metal around the bolt hole, scrape it off with a razor blade. Find the black H1/5 cable on the wiring harness and place the ring terminal at the end of the wire onto the bolt. Then place the bolt back into its original position. The alarm system is now grounded to the car chassis.
Set up the door trigger input. Find the violet-colored wire labeled H1/6 and connect it to any existing wiring that has an active 12V circuit whenever the doors are open. The wires for the dome lights are often the best place for this connection. Carefully strip a small amount of insulation from the dome light wire and from the tip of the violet wire. Wrap the copper of the violet wire tightly around the copper of the dome light wire, then seal the two together with electrical tape.
Find the blue wire marked H1/7. Connect this wire to sensor pins in either the hood or the trunk of your car. This allows the Viper 5000 car alarm to detect if someone is trying to break into these areas, and to instantly sound the alarm to announce the presence of an intruder. Simply use a screwdriver to attach the blue wires to a standard sensor pin.
Connect the negative door trigger input to the Viper 5000 car alarm. This is the green wire identified as H1/8. Similar to how the door trigger input (H1/6) was connected to the wire running from the 12V power source to the dome lights, the negative door trigger will be used on the opposite side of that circuit. The negative current typically passes into the wire that runs from the dome light back to the door switch. Splice the door trigger input (H1/8) into this wire at any point between the door switch and the light.
Establish a connection with the high current output from the dome light supervision relay. Identify the black and white wire labeled as H1/9. Plug the end of this wire directly into the circuit for the vehicle dome light. Expose the dome light circuit by opening the light compartment, the same as you would when changing bulbs. Once the circuit is visible, locate the plug port and plug the black and white wire from your Viper 5000 car alarm directly into the port.
Skip the white-and-blue wire labeled H1/10. This wire is used as a Channel 3 output and is not needed unless you install extra devices that require it. For the time being, just make sure there is no exposed copper at the end of the wire and push it out of the way. If there is copper exposed on the wire, wrap it with electrical tape so that it will be insulated and protected.
Hook up the output signal to make the parking lights flash. Use the white H1/11 wire for this purpose. Remove a small section of insulation from the end of the white wire using a pair of wire strippers. Also remove a small amount of insulation from the wire that connects the parking light relay switch to the parking light bulb relay. Be careful not to cut all the way through the wire. Twist the wires together so that the white wire is connected to the light relay wire, then seal the connection with electrical tape.
Ground the Viper 5000 car alarm when armed using the orange wire marked H1/12. Find a factory bolt on the body of your automobile that does not have any other components already using it for a ground. Under the hood or under the body of the vehicle are ideal places to locate these bolts. Scrape away any paint that may be under the bolt head and use the bolt to fasten the metal ring at the end of the orange wire to the body of the car. Your Viper alarm is now grounded to the vehicle whenever it is armed.
Test your alarm system. Your Viper 5000 should now be able to unlock your doors, light the inside of the car and prevent theft of your vehicle. Test the features of the Viper 5000 car alarm to make sure that all components are working to your satisfaction.
