Trunk mounted battery

I would not run it inside of the car -- Run it underneath instead. - Just my 2 cents - It's your car.

In my opinion it's just as safe and maybe MORE safe to run it right down the factory wiring channel under the sill plate

Thanks for the help guys. Should I add another cable from the motor to the frame for extra grounding?

The front battery is originally grounded TO THE ENGINE with the largest ground cable, and "jumpered" from either the battery or the engine to the body/ frame with smaller jumpers.

!!YES!! You need a BIG jumper from the engine to the body or else run a separate large gauge ground all the way back to the battery.
