Hi Lobster and Ashes, it’s easy to run cable through a D3, D4 Or an RRS, inside, down along the drive’s side door sills.
The link below is to an installation instruction thread for one of my Dual Battery Kits for a D3 but it’s the same for a D4.
There’s plenty of pictures to make it simple to follow.
Lobster, just out of curiosity, what isolator are you planning on using?
Also Lobster, the industry standard size cable for the break controller to trailer wire is BLUE 6mm Auto.
