Here are the pictures of the wires from the drivers side and passenger seats. I have confirmed that I have a steady 12 volts coming from the wiring harness.

I thought about a bad ground, but would it register voltage if I was too far from a good ground. Would I splice a ground in with the big black wire?

This is the passenger side. The wire nuts are not a permanent option. Wire colors are:
Black-big
Orange-big
tan
grey
orange
blue

Driver's side wire colors are:
Black-big
Orange-big
brown
brown
green
orange
black/white stripe
