Two ground wire prediciment.

I have two ground wires coming off different ends of the wiring harness. Should I connect them both to the same bolt on the chassis?

Re: Two ground wire prediciment.

Are you sure they are body ground wires?

or speaker ground wires?

If they are intended to connect to the battery negative ground (cathode) then yes you can connect as many as you like to the body at the same position, because the entire body is ground. Use a multimeter to ensure you have a good ground though and it flows well to the cathode terminal.

If they are speaker grounds then they loop to the negative terminals on the speaker, not the car body.

Post a better picture of those wires and your head wiring diagram.

Re: Two ground wire prediciment.

The one without the butt connector says chassis ground and that one is on the female end of the wiring harness and the other one comes from the Pioneer DEH-1300mp stereo portion of the harness. Does that help

Re: Two ground wire prediciment.

Do they connect together? I'm assuming you have the harness for the radio and the harness for the car so you don't have to cut the car harness off.

You said both ends of the wire harness. Typically one side has a plug and the other just has the bare wire.

Re: Two ground wire prediciment.

There is a piece that goes into my deck and sprouts a bunch of wires. Those wires are tied into more mores that come from a wiring harness purchased separately which has a female end which goes into the vehicle harness. Sorry for the confusion.

I cannot figure why I have two black cables . At least one is a chassis ground . Both black cables are coming from opposite ends of the wiring harness.

Re: Two ground wire prediciment.

One may be an antenna for radio, check to see if on the deck side you can read what it says.

Figured it out. It was the backup fuse. What a relief .

Re: Two ground wire prediciment.

Connect them together. If you experience noise from the alternator, then disconnect them and connect the one from the head unit to a chassis ground. The one from the harness is where the stock unit was grounded to.
