Everything seems simpke when you know it but it is never simple in real life.
Just to give you an update why I spent my Sunday and the Monday evening on this, I re-did it 2 times. After quite some time reflecting on the reinstalling, I elected to leave 6-8" of wires as extras ... Once all done, trying to tuck away the excess wires, I realised it was not convenient at all nor easy to do. So I shorten them by 6-8" .... and redid the whole thing again.
In all I spent on this harness 40-50 hrs .... remember , I did my version first and then used the Dynon pre-made harness !
