Fuse box WHITE cable, where does it connect? (4/8 awg)

[missionman]

Does anyone KNOW where this white hot wire goes? Its always hot.
I rerouted it years ago to the battery bank itself with no issues after installing a parallel LiFePO4 dual bank inside my 4runner and did a big wire upgrade years ago but Ive always had this white cable just running to my battery.

I think its supposed to connect to the alternator to power the system while car is running but im not sure. So this means the alternator has a black cable and a white cable connected to it?

Its been a while since seeing a OEM wired 2003 4runner v6.

My whole reason behind this was to isolate the alternators charge cable (black) that runs to battery and use that to charge my DC to DC Orion XS charger which then charges my LiFePO4 bank with certain voltage, etc.. This is why all my wiring has changed and im trying to place this white cable back where it belongs because I now believe its not actually a charge cable but rather it powers the system while running, it doesn't charge the batteries..is this correct?

I have no idea how to read that or how it corresponds to the white cable coming out of the fuse box. The white cable runs from a mount at the top of the fuse box, runs down into the harness and where does it attatch from there? Alternator? Starter? battery post?

Its a a constant live 12v cable even when car is off parked.

If anyone can look on their fuse box and see the white cable coming out into the harness and trace where this white cable runs to PLEASE let me know. I have a 2003 4runner V6.

How did you decide where to connect all of these mods? Did you guess?

Of course not. Why ask a sarcastic dumb question.

I have a Winch and a high draw audio system. Batteries are inside my 4runner not in the engine bay. I have a Orion XS charger which requires you isolate your starter and alternator so you can crank and the Orion can capture your alt power to convert it to a DC to DC custom charge voltage for 2 LiFePO4 batteries in parallel.

I dont need advice or explaining why to your curiosity.

What the hell makes you say i "guessed" at wiring. I took my harness apart years ago for big wire upgrade and Im trying to figure out where this WHITE 12v cable goes from the fuse box as its been tied into a distribution block and now i want it back where it belongs.

If you cant answer save your self projections for reddit

Simmer down.

That diagram clearly shows that it connects the main power output from the alt into the fuse box where it's split into 2 fuses (ALT, AM1), that then feed the rest of the system. It's got a sheathing on the alternator end which is why it doesn't appear white.

Thank You Cezar. Appreciate it.

Im going to ask AI what it thinks about your attitude......oh...the result just popped up.....it said "simmer down" So does that mean Cezar is actually AI?

Nicely done Cezar, nicely done.....
