1. All wires must be protected from mechanical abuse. Wires should be run in flexible metal or plastic
conduits.
2. Use 85˚ C [185˚ F] wire with abrasion resistant insulation. 105˚ C [221˚ F] wire should be considered
near hot surfaces.
3. Use a wire size that is appropriate for the module connector.
4. Separate high current wires such as solenoids, lights, alternators or fuel pumps from sensor and other
noise-sensitive input wires.
5. Run wires along the inside of, or close to, metal machine surfaces where possible. This simulates a
shield which will minimize the effects of EMI/RFI radiation.
6. Do not run wires near sharp metal corners. Consider running wires through a grommet when
rounding a corner.
7. Do not run wires near hot machine members.
8. Provide strain relief for all wires.
9. Avoid running wires near moving or vibrating components.
10. Avoid long, unsupported wire spans.
11. All analog sensors should be powered by the sensor power source from the PLUS+1 controller and
ground returned to the sensor ground pin on the PLUS+1 controller.
12. Sensor lines should be twisted about one turn every 10 cm [4 in].
13. It is better to use wire harness anchors that will allow wires to float with respect to the machine rather
than rigid anchors.
14. Electronic modules should be grounded to a dedicated conductor of sufficient size that is connected
to the battery (-).
Properly protect power input lines

Warning
Unintended movement of the machine or mechanism may cause injury to the technician or bystanders.
Improperly protected power input lines against over current conditions may cause damage to the
hardware. Properly protect all power input lines against over-current conditions.
