VX5/VX6/VX7 Adapter Cable
An adapter cable (VM1077CABLE) is available to attach the Thor VM3A to a vehicle
previously equipped with a VX5/VX6/VX7 DC power cable. The adapter cable has a
5-pin connector to match with the VX5/VX6/VX7 power supply cable on one end
and a 6-pin connector to match to the VM3A on the other end. This section
assumes the VX5/VX6/VX7 power cable is properly connected to vehicle power.
Refer to the X5, VX6, or VX7 Vehicle Mounting Reference Guide for details.
When this adapter cable is used, there is no provision for an ignition switch input.
Therefore the vehicle ignition monitoring function is not available when using this
cable.
Connect to VX5/VX6/VX7 Power Cable
1. Connect the adapter cable to the VX5/VX6/VX7 power cable by aligning the
connector pins to the power connector; push down on the watertight connector
and twist it to fasten securely.
2. The cable is rated for a maximum temperature of 105°C (221°F). Therefore,
routing this cable, it should be protected from physical damage and from
surfaces that might exceed this temperature. Cable should be protected from
physical damage from moving parts. 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.
Caution: For internal combustion engine powered vehicles:
Warning: For proper and safe installation, follow the Fuse Requirements for

Warning: Because the VX5/VX6/VX7 supports 10-60 VDC power input, verify
input voltages before using this adapter cable with an existing VX5,
VX6, or VX7 power connection installation.
