i've been searching the forums and i cant find an answer.

i ran a 10 gauge wire from the battery to a fuse box i installed under the passenger side dash. from this fuse box i installed a 12 gauge wire that runs behind the center console to the driver's side and it hooks to a switch which has the 12v end of the wire hooked to it ... i need to know where to ground the grounding end wire somewhere in the driver's footwell area.

i was hoping to test out the circuit for a second without a ground to see if it would turn on but when i flip the switch ... no go. anyways
