I'm assuming that your cab is the following:

But based on this, the load of the speakers don't calculate correctly.
4 x 16 ohms (series) = 64 ohms -- not useful
4 x 16 ohms (parallel) = 4 ohms -- half the specification
2 x 16 ohms (series) || 2 x 16 ohms (series) = 16 ohms -- double the specification
2 x 16 ohms (parallel) + 2 x 16 ohms (parallel) = 16 ohms -- double the specification
Is there any information on the jack plate or on the L-pad?
You could just wire it like all 4x10 cabs, and just hope that the crossover is correct.
