Wiring on frame rail

[BlueRidge2]

On both frame rails there are small holes drilled on the bottem from about the fire wall back to the rear axle. Are these holes for the clips that hold the wiring harnes to the rear lights and fuel pump or are they weep or drain holes? Thanks Bob

Thanks Greg. The pictures from John L show what I need to know. Bob
