Connect the Power
All LCR-II shipments typically include a 40' gray power cable (100', and 300' are also available) and a 5 A fuse.
Page 17 describes describe the best practices for routing the gray power cable to the truck cab's accessory panel.
40' Gray PoWer Cable
The gray power cable (PN 84046) is prewired to the J6 terminal on the CPU board at the factory. It includes two 16
AWG wires and a ground drain wire. The 5 A fuse should be spliced into the red 16 AWG wire as close to the power
source as possible.

Power must be supplied to the Epson printer as well. A 15' cable with a 12/24 VDC converter (825001) for printer
power supply is also available. The red wire of this cable must be spliced into the red wire of the gray power cable on
the LCR-II side of the 5 A fuse.
To connect power to the lCr-II and the epson printer:
1. Route the gray power cable to the accessory panel. See
page 17.
2. Splice the red wire from the printer power cable into the
red wire of the gray power cable.
3. Splice the 5 A fuse into the red wire. Make the splice
close to the direct power terminal connection in the
accessory panel and on the power side of the splice
made with the printer power cable.
Power Check
After the LCR-II has been installed, check to make sure that it powers up correctly. The LCR-II display and the printer
power light should come on when the truck's ignition is turned to the ON or to the ACC position. Make sure the printer
power switch is on. If the LCR-II or the printer does not power up, check the wiring and the connections on the LCR-II
CPU board against the manual.
