I hope you used an adapter to plug into the factory wires .... and if all your connections are correct ... I would verify that you have a good ground (touch a wire from a good clean bare metal directly to the radio's metal case) .... and check fuses .... Radio and clock fuses .... certain expeditions have amplifiers and subwoofers built into them and may not be compatible with your radio .... need more info

You need to have two type of harness one goes to your factory harness. The other one it goes to your radio so 2 different one's.
