I Wanna Relocate Battery To Trunk ?
#16
Theoretically attaching the ground to the chassis would work. Grounding is very important so you need a solid ground. It would be better to run another 15footer all the way to the back attached to the battery then you can put some more grounding points along the way. There are at least grounding points throughout the engine bay.

on my SC300 the previous owner just run a wire for the positive side of the battery through the fire wall and inside the car all the way back and for the negative is attached to the bolt for the spare tire, so far is working good for the 5 months I have the car, I will try to find pics if you want is not the best job or pretty but is works.

Yep. It will still work... I'm not saying it won't but it is good to have a solid ground all the way direct to the engine bay area or put more grounding points directly from the battery to the chassis.

I'd run it inside just so that I don't have to worry about it hanging down and get caught on something throughout the days/months/years... I would also look into that cutoff switch 1sicksc mentioned. Even though you are running 2 wires all the way to the trunk, I would also locate a section by the engine bay for a direct positive and negative terminal connection....
There was a guy here who owns a silver GS400 or GS430. I forget his screen name. His did an awesome job on this on top of it being supercharged. I'll find out and post his screen name. I'm sure he has tons of photos floating around.

Just run one + wire to the rear inside along the side trim to the positive on the battery. Attach the negative to the chassis on the trunk somewhere but make sure to sand the paint off in the spot your attaching the negative. Reason you should keep your grounds as short as possible. Running two years no problem.

you are right this is all you need. if you run the batt to the back it would be ideal to use 0 gauge to make sure proper charging is constant. and a stronger ca batt couldn't hurt. make sure to use a dry cell like optima though bc you guys wouldn't want your trunk to catch on fire after a acidic battery explosion.

Here is the right way
Ground Wire, Goes to stock location Then Battery.
Alternator wire, Goes to stock location then to a 120A Breaker then to Battery.
Starter Wire, Goes to stock location then Battery.
Fusebox Wire, Goes to Batter for the cut off I had to redo the fuses.
The Clear on goes to the Fusebox
Cut Off Swich, no picture of the wiring just location.
Sorry for all the half a$$ed Photos once my Driveshaft is done I can drive my car back home and I will take alot better photos but if you need anything explained let me know.
