2.7.1. EX4 Plus: Connecting the Signal Harness
The 5-conductor signal harness is used to connect to the various signals in the
vehicle, including turn signals, brake lights, stop-arm, and warning lights, for
example. Always connect through a fuse-protected circuit. The signals can be
activated from 12 VDC (Active
HIGH) or 0 VDC (Active LOW). See “3.2.7. Using
the Signals Menu” on page 3–18.
The indicators can be hooked up to any signal as the text for each indicator can be
easily reprogrammed. For example, Indicator 2 can be connected to the Wheel
Chair Lift signal, and the text could be changed from STP to WCL.
If the signals are not being used with the system, then this harness does not have
to be installed.
