Set up the control box to match your vehicle
.
The tachometer must be set to match the number of engine
cylinders and the fuel gauge must be set to match your fuel sender resistance curve or the instrument system will not
display correctly. The control box can read seven common fuel level sender resistance values. If your sender is not
listed, the system can be programmed to a custom sender (see full manual for details).
