I used a harness called (I think) bare wire mount. Worked great for me but it does have all the other wires included that you were not wanting. I also mounted my 796 in the panel with out using an Airgizmo's mount and I like that installation much better. I used the bare wire connector and fastened a backing plate to it , cut out the panel very carefully to fit around the perimeter of the 796 and bolted the backing plate to the panel. In my opinion the installation looks just like a panel mount GPS. In my Cub, I used the Airgizmos mount for my 396 and I find it bulky looking and much harder to remove and re-install.
