Also a phone mute wire i think.

Does your car have radio controls on the steering wheel?

no phone and no steering control

You don't have to have them, the connector is there for models that do.
If your putting in an aftermarket unit as a general rule that you can ignore this plug.

Btw, do you need 2 threads open on this ?
