All previous wiring was marked which made the swapping easier. I had to add a power wire from VPX to the EIS panel switch to feed the controller unit. The Coil Pack also needed a VPX wire to feed those coils. Removed the key switch, marked and cut out the enlarged replacement switch panel opening. The nearby panel area had 6 switches (one unassigned). I had to rearrange the remaining 5 by drilling a new single hole below the originals. So I now have Master and Avionics on top, then Co-pilot Stick Ground and APRS below and finally Alternate Static on the bottom.
The right P-Lead and P-lead shield get removed. The right Tach gets spliced to the EIS tach wire.
New cutout will encroach on the top two switches. All need rearranging.
