Wiring the System
Once everything is securely mounted, you can begin wiring the various components of the
system, one at a time.
 ComNav strongly recommends that ABYC wiring standards, or the equivalent
for your locale, be followed.
Signal Processor Unit
Start by removing the Wiring Cover from the SPU. It is held in place by two knurled plastic
nuts (see Figure 34).
Set the cover & nuts aside – they will be re-installed once all the wiring of the SPU is
complete.
Figure 34 – Removal of the SPU Wiring Cover
Connectors on the SPU
With the wiring cover off, all the SPU’s connectors are visible & accessible.
Each connector is a pin receptacle, with the pins sized according to how much current will be
carried – bigger pins for higher current. Each pin has a signal name, rather than a number, to
make it easier to match wires with pins (see connector label, below).
