top of page Power Connections
Power (+) 12V DC
Connect to the positive terminal of the battery using the appropriate size fuse(s). See your installation manual for more info.

Ground (-) 12V DC
Connect to any clean and solid chassis ground source. See your installation manual for more info.

Ignition (+) Input
Connect to a source that has (+)12V DC only when the ignition key is in the run and start positions. See your installation manual for more info.

top of page Triggers
Door Trigger (-) Input
Connect to the wire(s) that only shows (-) ground when any door is open. If you're installing an alarm in a vehicle that does not have a common door trigger wire, you will need to connect two or more together using blocking diodes. (diagram)

Door Trigger (+) Input
Connect to the wire(s) that only shows (+) positive 12V DC when any door is open. If you're installing an alarm in a vehicle that does not have a common door trigger wire, you will need to connect two or more together using blocking diodes. (diagram)

Hood / Trunk (-) Input
Connect to a wire or switch that provides ground (-) when hood/trunk is opened. If positive (+) 12V DC is present when hood/trunk is closed on the same wire, use a blocking diode with the cathode towards the switch.

Sensor(s)(-) Input
Connect to the (-) negative output of a sensor or triggering device. Many alarms will have additional (-) negative inputs to accommodate additional sensors or ports to allow their proprietary sensors to plug directly into them. Some offer both. If the alarm only has one input and you need to connect two or more sensors, use a blocking diode on each output wire of each sensor.

top of page Additional Inputs
Brake (+) Input
This connection is only needed for remote start units. Connect to the wire that only shows (+) positive 12V DC when the brake pedal is being pushed. This switch is usually located just above or behind the brake pedal onmost vehicles.

Parking Brake (-) Input
This connection is typically only needed for some manual safe remote start units. Connect to the wire that only shows (-) ground when the parking brake is engaged.

top of page Valet Switches
Valet / Override Switches
Many of today's alarms have a port to plug the valet/ override switch(es) directly into them. If not connect one wire of the switch(es) to ground and the other to the specified input of the alarm. If your alarm requires a positive input, then connect the first wire to (+) 12V DC. See your installation manual for more info.
