The wire in the trunk MAY be for an amplifier that a previous owner had installed but just didn't remove, have to look to see if there is a matching wire behind the radio.

For the plug that should be for the cruise control brake pedal position switch, if your car doesn't have cruise control then it may just be wired for it, if it does have cruise control then you should plug it in to a switch that will be right above the brake pedal.

Thank you! No cruise control so that explains the connector. I'll have to take a look at the radio.
