I am new to audio diy part.

I used an littelfuse add a circuit kit to get +12v from fuse box under drive side;

But there is no 0v or negative or ground wire there. Where do people hook the negative terminal?

I know the frame is 0v/negative, which region is easy to hook the negative terminal?

Thanks.

The whole vehicle is a negative (ground). Anywhere you can find bare metal is a good negative. If you're getting the positive from under the seat, then you can use one of the four post that secure the seat to the floor.

look underneath the driver side dash (stick your head way under), and look for any metal bolt or screw that is bolted to the frame. You still need to use a multimeter to test if it's a true ground because the car is made with spot welds and not all metal parts under the dash is a perfect ground.

Once you find one, put a ring terminal on your ground wire and install it. Lastly, make sure you watch where you run your ground wire under the driver's side because you have many mechanical moving parts there (e-brake; brake pedal, gas pedal). Make sure nothing gets caught or pinched.

I just brought the claw wire to the lug, which was more convenient and electrically equivalent. Essentially, what you are doing is coupling the tuners, strings, and bridge assembly to signal ground through the spring claw, preventing unpleasantries.
