just have to figure out how to install some lights in the holes.
Find an old harness and harvest the light sockets for your truck.
If you can't locate an old harness, try NAPA, Auto Zone, Advance, etc.
The photos below show what you need. The single wire uses the cluster housing as the ground the 2 wire has a separate ground wire.
Just run a wire from the sockets to the light switch.
