12 VC5090 Vehicle Computer
• On gasoline, diesel or propane vehicles, take the power from as close
to the battery terminals as possible, and avoid using existing wiring.
• All fuses must be as close as possible to the power source.

12-24V Gasoline, Diesel, or Propane Forklifts
• All power wiring must use the supplied power cable.
• Fuse in positive rail = 20A
• Fuse in negative rail = 20A
• Fuse in switched positive = 1A
• Keep the path between the battery and the vehicle computer as short
as possible, and away from any part of the ignition high tension
system.
WARNING! A lead acid battery can leak hydrogen gas. A spark
anywhere near the battery can cause it to explode.
Always make your final connection to power as far
away from the battery as possible, i.e., connect the
power cable to the battery first, then the vehicle
computer.
CAUTION Use extreme care when routing and securing this
cable from the vehicle computer to the vehicle
power source. Hazards associated with improper
wiring can be severe. To avoid unintentional contact
between the wire and any sharp edges, use proper
bushings and clamping where the cable passes
through openings. If the wire is subjected to sharp
surfaces and excess engine vibration, the wiring
harness insulation can wear away, causing a short
between the bare wire and chassis. This can start a
fire.
