5. Wiring the OHM653
The following pages display wiring diagrams for various
OHM653 configurations.
Read the following precautions before wiring your system.
•
Disconnect the negative battery terminal before making
any wiring connections.
•
Be particularly careful where you route wires. Keep them
away from the engine, exhaust system, etc. Heat may
damage wires. Sharp edges can pierce wire insulation
and cable jackets, causing short circuits, damage to the
vehicle, blown fuses, and system failure.
•
If the fuse should blow, make sure all connections are
correct and no wires are damaged before replacing the
fuse. Always use fuses that are the same amperage value
as the original. When replacing a fuse, never let the battery
side touch any metal part or any other wire.
