This unit comes with a lot of extra cords. You get what’s in the picture. This unit does need to be cleaned up as there is grease and other shop residue on the cords and unit. I plugged the main scanner unit into my cigarette light and it powers in and makes noise. I do not have an older car to test the functionality of the unit. I also do not have the means to test the cables either. This is being sold as untested. You get everything in the pictures!!
