Battery Cable Route

[Bakaruda]

I would like to know what the group thinks is the best way to run the main cable. I keep going back and forth on the under vs inside. Please provide your ideals and pictures if you have any. Thanks in advance.

In side it will be better protected, but you'll need a grommet or bulkhead to go through the body. I'm running mine inside the car personally. That's how GM does it on new cars with the trunk mounted batteries.

+1 for inside, for mine I placed the battery on the passenger side in the rear, ran the 1/0 along the passenger Side of the transmission and passed it through a grommet close to the starter. charge wire runs through a seperate grommet from alternator back to the battery via the drivers side of the tunnel.

Curious, what's the thinking behind running a separate charge wire from the alternator to the battery?

It’s usually done only when a solenoid is placed in the trunk to make the battery to started lead hot only during cranking.

I appreciate the replies. I have always ran it under the car. I may go the inside route this time.
