EDI Electrical System Precautions
NOTE: The following precautions apply to all EDI model Engines.
CAUTION
Avoid damage to the Electronic Direct Injection (EDI) electrical system and compo-
nents. Refer to the following precautions when working on or around the EDI electri-
cal harness or when adding other electrical accessories:
• DO NOT tap accessories into engine harness.
• DO NOT puncture wires for testing (Probing).
• DO NOT reverse battery leads.
• DO NOT splice wires into harness.
• DO NOT attempt diagnostics without proper, approved Service Tools.
Instrumentation
GENERAL
We recommend using Quicksilver Instrumentation and Wiring Harnesses. Refer to “Quick-
silver Accessories Guide” for selection.
NOTE: If using other than Quicksilver instrumentation and harnesses, refer to manufactur-
ers’ instructions.
The six basic gauges that must be used with the engine are:
• Tachometer
• Oil Pressure
• Water Temperature
• Voltmeter
• Cruise Log (Engine Hour Meter)
• Trim Gauge
When using the instrumentation, instrument harness wire connectors are labeled. It will be
necessary to connect them onto the individual Quicksilver instruments, switches and En-
gine System Monitor panel. The instrumentation harness ends are provided for connection
into the appropriate extension harness ends. The wiring harnesses will then be ready to
route to the engine.
On dual station applications, oil pressure and water temperature senders (on engine) must
be changed.
Additionally, changes are needed in the primary station key switch wiring to allow use of start
and stop switches common on dual station panels. Refer to instructions in kit.
When routing any wiring extension harness back to the engine, make sure that the harness
does not rub or get pinched. Be sure all extension harness connector collars are secure.
Fasten harnesses to boat at least every 18 in. (460 mm) using appropriate fasteners.
