Wrong harness. Type in 70-1858 on ebay, thats the one you need.
Do you have the centerpiece in your truck? You will need a new one that houses the radio, but you will need the clips and the AC vents off the center piece in your truck.
Unfortunately, your truck isnt that normal of an install. You have to find the factory amp which is close to the firewall by your gas pedal. You'll have to take the wires out of that and plug that into your 70-1858 harness.
