2.2 Review the "EDC Wiring Work Sheets:"
There are a number of probes and extension cables that will need to be installed. The key to keeping the
installation simple is to organize the work using the "EDC Wiring Work Sheets"
"EDC Wiring Work Sheets" "EDC Wiring Work Sheets" "EDC Wiring Work Sheets" "EDC Wiring Work Sheets" supplied with this kit.
Review the functions assigned to each EDC input on the EDC Wiring Work Sheets. The work sheets are
prepared at the factory with the functions and probes already assigned.
2.3 Verify You Have all the Probes, Modules, Transducers and Cables:
The three EDC 37-pin D-sub connectors and the CGR 25-pin D-sub connector are pre-wired at the factory.
The three EDC connectors are marked Top, Middle and Bottom. The EDC Wiring Work Sheets provide a
list of the probes supplied with this kit.
A. Check that you have all the probes listed on the EDC Wiring Work Sheets.
B. Check that the three EDC 37 pin-D-sub wire harnesses are provided with the proper wires for
each of the probes shown on the EDC Wiring Work Sheets.
C. Check that the CGR 25-pin D-sub wire harness is provided.
2.4 Install the CGR Display:

view of the CGR display without any visual obstructions. The CGR display is installed from behind the
panel into a standard 3 1/8" hole.
CFR 23.1321(a) states, “Each flight, navigation, and powerplant instrument for use by any required pilot
during takeoff, initial climb, final approach, and landing must be located so that any pilot seated at the
controls can monitor the airplane’s flight path and these instruments with minimum head and eye move-
ment.” To comply with this requirment mount the CGR-30P 21" or less from the pilot’s visual centerline to
the middle of the instrument. The pilot’s visual centerline is a perpendicular line from the pilot’s eye to the
instrument panel. In some aircraft, the visual centerline falls to the right of the Attitude Indicator.
If the CGR display is not installed within 8" of the pilot’s visual centerline, the external Master Caution and
Warning Lights should be installed. Installation of Master Caution and Warning Lights are covered in this
manual.
