wiring trouble

The jumper box on the passenger side.The small red one.The wire coming in to it.Is a power wire or what.I have it wired going out.It was never apart.I need help

You talking about the one behind the battery, that always seems to be missing the top? That's a power distribution block, there should be a large wire going into it from the battery, and a cluster of smaller wires coming into it from the harness.

Thanks fastbird.thats the one.i think my stereo is on it.Im not sure but I think so.

What trouble are you having? Everything on that block is a constant 12v source.

On my LG G4

If your stereo was installed with a harness adapter then it shouldn't be wired to that block. Unless you're talking about an amp, then that could be wired to that distribution block. That's where I hooked mine up since these cars use the side post battery terminals.
