Quick follow-up question:

The stock diagram and Becker harness uses the outer braid of the
shielded wire as a ground connection.

Could I use the inner braid as the signal wire and a _separate_ wire
as the ground wire? This would avoid requiring me to solder the ground
connection onto the outer braid and make it easier to fab up the wire
harness; but I'm dumb when it comes to electrons so I don't know if
the ground connection is needed in order for the shielding to be
effective...

Help?

Thanks!
