  We study the dynamics of a scalar field with Kaluza-Klein type couplings to
cold dark matter and an isotropy-violating vector field. The vector coupling,
$f^2(\phi)F^2$, has been studied thoroughly in the context of inflation
recently. We generalize the model to a dark energy context and study the
cosmological consequences. We find a rich set of exact anisotropic power-law
solutions and identify a strong vector coupling regime where the anisotropy is
controllable and all solutions are close to the LCDM limit.
