• Then attach the two wires at the other end of

the fused cable to a DC fuse/terminal block on

a vehicle in which you are mounting the

MultiConnect WF device server.

• Connect the red wire to the "+" positive and

the black wire to the "–" negative. Be sure the

GND connection is correct.

Warning: Over-voltage protection is

provided on the device. To ensure
