Power Cable Identification
The DC power cable is included with the dock and is one of the two styles below:
Power cable with right angle connector and 6 wires:
Power cable with straight connector and 4 wires:
Note: Correct electrical polarity is required for safe and proper installation. See
for additional wire color-coding specifics.
The Thor VM1 DC input wires (Red, Red/White DC+ and Black, Black/White DC-) and
the Blue ignition input wire are galvanically isolated. The Green ground input is used for
electrostatic discharge (ESD) protection.

connected to a fused circuit on the vehicle. If the supply
connection is made directly to the battery, the fuse should be
installed in the positive lead within 5 inches of the battery's
positive (+) terminal. Use VM3055FUSE (or equivalent) to
install the fuse as shown below:
For all voltages, use the 3A fuse from the kit or a slow blow fuse that has a DC voltage
rating greater than the vehicle input voltage.
Twist the red and red/white wires together and
twist the black and black/white wires together
