Wiring Overview
EFIS-D6 Installation Guide 2-3
The pin assignments for the female 25-pin harness are repeated below. Note that the pin numbers
are labeled on the face of both the female and male connector. Each connection on the harness
supplied by Dynon is color-coded. These colors are listed in the following chart.
For wires that are marked “(Unused in EFIS-D6)”, terminate these wires in an appropriate
manner (insure that they do not short). Dynon recommends not cutting or removing these wires
to preserve the option of upgrading the EFIS-D6 to an EFIS-D10A
