How do I add a battery to my car?
Get a small heavy-duty ‘junction block’ or ‘distro / distribution block’ (small electrical connector box containing terminal posts). Mount the block in a secure / convenient location in the engine bay. Re-route your stock wires to the block’s terminals, then add two new lines from those terminals to the battery posts.
Does the cable reach across the top of the battery?
I figured the cable would reach across the top of the battery and it does not. I know this battery is popular for tacomas and the like so I was wondering what good ideas you guys had for me as to how I can simply extend the positive cable about 3-4.
How to add a fuse to the battery terminals?
If it is only a short distance from where an original battery was to the new battery terminals then you could use it as a convenient point to add a fuse block and cut out. Mount a board on near the cable entry and mount on it an ABS box with bolt post terminals to fit a fuse or two.
How to re-route wires from stock to battery?
Re-route your stock wires to the block’s terminals, then add two new lines from those terminals to the battery posts. This approach is ‘modular’, preserves the stock wiring harness, and allows for flexible reconfiguration (of the new lines) if you need to do so later.
