It is not difficult task to wire but it takes time. I don't know what I can say about my day today as I did not work yesterday. I have made the radio harness and ran in problems when I tried to close the Dsub cover as I had 2 wires that snapped. But overall, it worked although I have not yet tested the conductivity, but I am assuming it is OK.
So today I wired the radio, SV-Com Panel & have not finished the intercom connection.
I did procrastinate trying to figure out where to mount the two regulators for the alternators ... I have not made a decision on this yet.
Lots of wires & trying to keep it neat is not simple
