Question about using wire headers & connectors on both ends

Hello, I just received my Nava 909 kit and am starting to build it.

Quick question, would it be ok to use headers & Molex connectors for both J8 and J5? In the instructions, it shows wires soldered on one end at J8

Has anyone else added headers & molex connectors to both ends of their wires when building?

Thanks!

This may have been a silly question but in case it helps any other newbies like myself, I did end up adding wire headers and connectors on both ends and it worked out really well. Everything still fits in the case and it also provides the flexibility to connect and disconnect the boards as needed.

Connectors on both ends makes a more reliable installation than soldering if you move the cables a lot.
