It won’t hurt if you go the wrong way
So just experiment
But yes from the transmission end of the cable looking into the cable you need to go ccw
Because when facing the speedometer the needle is moving clockwise so you have made one half rotation in plane looking at the needle from the tranny end of the cable
When you drive in reverse really fast the cable spins the wrong way in normal operation
You speedo handles that case just fine
The clock spring is not stressed because the needle cup is bottomed out on its stop
