After programming and setting options on your computer you are now ready to install the FT-820. Here is a more
detailed description of the wires of the FT-820.
Connector: 6-Pin (Pre-wired Antenna Cable)
Pin 1 Red - Constant 12V positive (+) output.
Pin 2 White - TX output. This wire transmits the signal to remote.
Pin 3 Orange - Constant 5V positive (+) output.
Pin 4 Yellow - RX input. This wire receives the signal from remote.
Pin 5 Black - Negative (-) ground.
Pin 6 Blue - (RX/TX) Control
Connector: 10-Pin
Pin 1 Brown - Siren 12V positive (+) output. Connect this wire to the (+) wire located on the siren. To change siren
output settings, review Option 2-07.
Pin 2 Blue - 250mA negative (-) output when armed. This wire provides a ground when armed to activate a starter
kill relay. Caution: When this wire is being used to trigger aftermarket accessories it must be diode isolated.
Pin 3 Yellow - 250mA negative (-) Disarm output. This wire is used to disarm the factory alarm on some of the ve-
hicles.
Pin 4 Yellow/White - 250mA negative (-) Rearm output. This wire will rearm the factory alarm if connected. It can
also be reprogrammed to trigger the factory horn or can be used as an Auxiliary 1 output.
Pin 5 Light Blue/White - Brake 12V positive (+) input. This input must be connected as it provides a shut down for
the remote start. The proper wire will test (+) 12V while the foot brake is pressed.
Pin 6 Light Blue - Parking / Emergency brake negative (-) input. This input is required for manual transmission/reser-
vation and turbo-timer mode. The proper wire will provide a (-) trigger when parking / emergency brake is set.
Pin 7 Orange - ISO9141-2 wire. This wire must be connected to the OBD-II connector. This is typically connected
to pin 12 (Except for KIA Amanti which is located at pin 7) on the OBD-II connector.
Hyundi Azera requires both
CAN High and CAN Low plus the ISO wire connected
. Future Hyundai and Kia vehicles will have CAN High and
Low wires. Firstech does not recommend using any T-Taps or scotch locks on these wires.
Pin 8 Grey - CAN Low wire. This wire will be connected to the CAN Low wire on newer Hyundai and Kia vehicles.
This is strictly a data wire. Firstech recommends not using any T-Taps or scotch locks on these wires.
Pin 9 Grey/Black - CAN High wire. This wire will be connected to the CAN High wire on newer Hyundai and Kia
vehicles. This is strictly a data wire. Firstech recommends not using any T-Taps or scotch locks on these wires.
Pin 10 Pink - Start trigger wire. A single ground pulse on this wire will activate the remote start process. This is most
commonly used when adding a remote start to a factory keyless entry system.
