I'm not 100% sure about this, but believe the cable terminates at the valve with a sleeve that is attached to the valve stem/shaft with set screws or some other form of clamping device. If you are lucky, you may just have to reattach the cable to the shaft. You still should be able to access the shaft to be able to move the valve open to dump the tank without connecting the cable. It would be advisable to get a valve that can be connected to the waste connection where you connect your waste hose, this way you can get the valve open, then dump using the added outside valve.
