You've got it correct. The furthest one is +.

If you have an ohm meter you can verify this by inserting an instrument cable and connecting your meter leads to the furtherest connector lug and tip on the other end of your cable.

LOL.

It's always a good idea to do a battery test on your wiring to make sure you have the polarity correct in case the (+) on the driver is labelled incorrectly.

Connect the negative wire to the (-) on a 9V battery. Any small alkaline type battery will do. Momentarily tap the positive wire to the (+) terminal battery terminal. If it is wired correctly the speaker cone should move outward. Reverse the battery and the cone should move inward.

If your cab has more than one speaker, they should all suck or blow in unison.
