When routing the EDC wire harnesses refer to the Top, Middle and Bottom "EDC Wiring Work Sheets" found at the

back of this manual. Ensure no wires obstruct the freedom of travel of any controls.

3.1 Attach the three EDC 37-pin wire harnesses to the EDC:

Secure the connectors using the supplied mounting screws.

3.2 Connect the EDC Harness to the Temperature Probes:

Route each of the temperature cables in the EDC harness to the appropriate temperature probe. Cut the wires to

length, install the appropriate connectors (see the “Working with Connectors” section of this manual for more

information) and connect to the temperature probe. When connecting to a temperature probe, leave some slack in the

cable exiting the probe to prevent damage to the probe over time.

3.3 Connect the EDC Harness to the Pressure Transducers:

Route each of the pressure cables in the EDC harness to the appropriate pressure transducers. Cut the wires to length,

install the appropriate connectors (see the “Working with Connectors” section of this manual for more information)

and connect to the pressure transducer. When connecting to a pressure transducer, leave some slack in the cable

exiting the transducer to prevent future damage to the transducer.
