Harnessing is a critical consideration when designing any electrical system. There are many things that go into robust and effective harness design. I’ve detailed my knowledge on harnessing in my harnessing guide.
I’ve also included a breakdown of the connectors used on M23 as well as my personal recommendations for connectors here.
If you’re looking for the harnessing diagram for M23, you can reference M23’s Harnessing Diagram.
