Hey, please please please try to document the dash swap and gd dash harness work. I can't, for the life of me, find any concrete info on what needs to happen to make the gd wirin plug into the Rs chassis. If the gd harness can be unpinned and have the Rs connectors inserted so it plugs into the Rs vehicle harness, ill be quite happy. I much prefer swapping pins/connectors over cutting and soldering.
I'm also wanting to see what you do for the dash beam. I'm hoping to see a good way of doing it rather than the easy way.
