The item in my kit
I bought Victron MK3-USB VE.Bus Interface as part of my camper van equipment.

Where it fits my build
On Day 104 I pulled the roof wiring through the PVC route with fish tape and brought the cable groups into the van. I fitted plastic trim around the roof opening where the wires passed through.
I also finished the remaining light-wire connections, fitted the junction-box covers, joined the remaining PVC sections and tightened the metal ties around the route.

My build notes
This stage pulled together several earlier sessions of drilling boxes, fitting glands and arranging the roof hardware. The final cable entry was the point where all those separate roof routes met.
My notes show how much of the work was physical organization: pulling cables, keeping entry points accessible and closing boxes after the connections were finished.
The route into the van was a layout problem as much as a wiring task.
Alternative products
Two alternatives to compare
The MK3-USB-C changes the computer connector, while the VE.Bus Smart Dongle provides Bluetooth monitoring and control functions rather than the same wired configuration interface.
Victron MK3-USB-C Interface
This interface connects VE.Bus equipment to a USB-C computer port. The adapter body provides the socket for a separate VE.Bus cable.
