Connect Vehicle Electrical Connection - Honeywell Thor VX8 User Manual

Connect Vehicle Electrical Connection

1. Please review the proper wiring schematic illustration, later in this section, before beginning power cable install.
2. The computer must be powered off.
3. Begin by connecting the power cable to the Thor VX8. Work from this connection with the last connection being to the
vehicle's power source.
4. Route the cable from the Thor VX8 to the DC to DC converter and, optionally, the screen blanking box. Cut the cable to
length and strip the wire ends. If the screen blanking box is not used, do not strip the green and yellow wires.
Route the power cable the shortest way possible. The cable is rated for a maximum temperature of 105°C (221°F). When
routing this cable it should be protected from physical damage and from surfaces that might exceed this temperature.
Do not expose the cable to chemicals or oil that may cause the wiring insulation to deteriorate.
Always route the cable so that it does not interfere with safe operation and maintenance of the vehicle.
