2.7.1. Connecting the Signal Harness
The 5-conductor signal harness shown in Figure 2-9 connects to the various
signals in the vehicle, including turn signals, brake lights, stop-arm, and warning
lights, for example. If the signals are not being used with the system, then this
harness does not have to be installed.
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 3–17.
The wire colors for wiring to the indicators and default text are described in Table
2-2. 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.
To connect the signal harness connector to the Smart-Link module:
• Connect the signal harness connector to the
SIGNALS connector on the Smart-
Link module.
CAUTION: Power and ignition harness connection
To ensure proper performance, connect the red and black power wires to points as close to
the battery as possible. Never connect the ground wire (black wire) to the vehicle chassis
by drilling a hole into a panel and using a sheet metal screw. The ground connection will
be corroded very quickly and the performance will be compromised.
