I bought my 08 SE a while back so I don’t know it’s history other than wrecks. The truck has a new big screen radio. I want to Remove the radio. The radio is a Dual. So I went and bought original radio to install. I was removing it and whom ever installed it used a new harness to fit radio. Original one is missing. So I can’t just swap it. I need the harness that fits on original radio and onto the original harness. Or is there another way? All wires are labeled. It would be a mess to splice it all. I think all I need is a harness that mates with harness under dash and to radio harness. Is there a part number for the harness or do I splice it?
