[QUOTE="keep_hope_alive, post: 7337635, member: 576029"] no alternate spot, must go to the battery directly. the power wire needs an inline fuse within 12" of the battery, the fuse holder should be firmly attached, you do not want the wire holding up the fuse holder. wire should be zip tied every 6-8" or so in the engine bay, and should be protected in split loom. where you penetrate the firewall, you need a grommet. grommet can be rubber or plastic, but you cannot let the wire insulation pass through a metal opening without a grommet. if you use a factory rubber grommet, you are fine. if you use a factory hole, you need a grommet. lastly, make sure the hole is sealed, otherwise the power wire can wick in water and get your floor wet. i use a streetwires firewall grommet whenever possible. if not, i use a rubber grommet and silicone to seal the penetration.
