Additional Installation Information & Material Requirements

GlowShift Gauges Approved Conductor Wires: Successfully installing GlowShift Gauges may require lengths of wire (sizes and quantity
depend on vehicle, gauge type, gauge location and / or sensor location). For correct and proper GlowShift Gauge installation and operation, the
use of 18 Gauge (wire diameter) automotive grade conductor wire with sheathing is recommended for one or more gauges per vehicle. When
installing and routing wires from the engine compartment, to inside the vehicle cabin, always employ the use of a rubber grommet. This will
prevent and deter the stripping of power supply and / or sensor wires that is necessary to deliver vital statistics about your engine to your
GlowShift engine monitoring instruments. Never use wire nuts to fasten or bound vehicle / gauge or sensor wiring. Always use securing crimp
connectors or solder individual wire junctions together for optimum gauge installation and operation.

GlowShift Gauges Approved Installation Accessories: GlowShift Gauges may require the installer or user to provide additional products,
accessories or adapters for the correct installation and operation of a gauge or sensor, as per the GlowShift Installation Instructions. When
installing and routing hoses to or from the engine compartment, to inside the vehicle cabin, always employ the use of a rubber grommet. This
will prevent and deter the stretching or pinching of hoses that is necessary to deliver vital statistics about your engine to your GlowShift engine
monitoring instruments.
