Need to install radio but plugs are gone
depending on u installing aftermarket or factory radio, the plugs in your expedition dont really matter, its the ones on the back of the radio your installing that need to be there. first you have to find out which wire/wires are hot (+) and which ones are ground (-) you can do this with a very helpful tool called a test light. use metal of car to find your hot wire, then use the hot wire you just found to locate a suitable ground location, can be wire or metal of vehicle. then about your speakers, they will usually be different colors, the easiest foul proof way is to partially remove the door speakers one at a time, when you see what colored wires connect it, it will be the same ones to connect in your dash. good luck!
