5. Installation
Installation must be done with the harness disconnected from the Input
Expander and with the battery disconnected from the vehicle. It is very important
that the wiring harness is as short as possible and any unused wire must be
cut. Never roll any leftover wire in the harness. This will avoid any interference
issues, common in any electronic equipment.
The harness must be protected from contact with sharp parts of the body and
frame that may damage it and cause a short circuit. Watch out especially when
going through holes, always use rubber grommets or similar protections. In the
engine bay, route the wires away from excessive heat and any moving parts.
Insulate the wiring harness whenever possible.
5.1 CAN Network
The CAN network allows the ECU to access the FT Input Expander’s channels.
In addition, data reading is fully integrated through the FT Manager software.
CAN Network Connection
The FT Input Expander harness has 2 exclusive connectors for the CAN network
connection with other FuelTech products.
1 - Female Connector
2 - Male Connector
3 - Terminator
Plug the male connector (2) into the female connector of the ECU. In case you
have more than one equipment connected to the CAN network, it is necessary
to remove such equipment’s CAN terminator and plug the Input Expander’s
male connector (2) into this equipment’s female connector.
The terminator (3) must always be installed in the female connector of the last
equipment connected to the CAN network, this reduces possible noise levels
captured by the CAN network.
The male connector (1) must NOT be plugged into the female connector (2)
of the same Harness. If this is done, the FT Input Expander CAN Network will
not work.
