Installing equipment

edge of the panel, route the wires with wiring for the air probe
harness. Secure loose wiring to the perforated panel with cable
ties.

of the column) so it is in a secure position. Position wiring from the
perforated panel so it rests in the cable well next to the orange
connector at the rear of the module (see Figure 20 on page 181).
Position the perforated panel and install the screw that secures it at the
LED mounting bracket.
a. Slide the LED ring over the LED (see Figure 21 on page 181). The
