[QUOTE="keep_hope_alive, post: 7337648, member: 576029"] you can't move the fuse box... too many wires there. you don't need actual access on the firewall side. here is the process: locate a spot that is flat and open on both sides (you've done this). buy a properly sized firewall grommet, streetwires makes some that are very nice, otherwise a standard grommet can work. drill a hole perfectly sized for the grommet. file off the sharp edges on the hole insert the grommet route the power wire through the hole and grab it from the engine bay. you can push the wire in the direction you need. note: do not just pull the wire from the engine side, you're likely to loosen the grommet. carefully push wire through from the cabin side, taking note of the grommet. route the power wire away from heat and moving parts, routing with factory wires is good. protect the wire in split loom and zip tie to keep firm once you're all done, hit the hole/grommet/wire with some silicone [/QUOTE]
