from the front batt... run it down to the frame then follow the frame all the way back to where it needs to come into the vehicle. I did mine that way this time, but not every time. Its a BISHHHH drilling a 1" hole all the way through the floor of an S10 though. actually two holes, one for power and one for ground going directly to frame from my rear batts. use a grommet when going through the body to make sure your car dont go boom.
