95 maxima Power Wire Install

Ok i have a 1995 NIssan Maxima and i need to run a 0 guage power wire. Ive looked under the hood and i cannot find a suitable hole let alone any hole to run the wire through the firewall, If anyone has drilled there own or ran a power wire through an existing hole, please send me a pic or the information showing me where to drill or put it through. thank you.

yikes, that is a fat wire?  where's it going anyway?

ive got a 98 i dont know how differant they will be, but if you look on the passenger side of the engine bay all the way at the back on the firewall follow the hose that the wiper fluid goes through. there should be a gromet about 2 inches wide that comes out right below the passenger side of the dash. just take a box cutter or knife or something and cut an X in the gromet and use a wire coat hanger to ger the wire trough.
