i am doing the same i looked on ebay and purchased single din shaved it to fit my unit and it looks good if u have factory bose there is no harness

 

I have a 98 eldo which had the Bose system in it. I searched the internet and couldn't find the mounting bracket that looks plush with the eldo, so I went to Circuit City who was able to special order one for $28. As far as a wiring harness, if you have the Bose system, there is no wire harness. You will have to manualy bypass all the amplifiers. Make sure also when you bypass all the amplifiers that your remove the amplifier fuse which is located in your trunk. Any other question contact me at jluver777@yahoo.com

I couldnt figure out if I had factory Bose. I didn't see it writen anywhere on the books that came with the car or anywhere in the car. I took out the trunk carpet and on the right side I found an amplifier. If I have an amplifier does that mean its the Bose package, or is the amplifier in all versions. Thanks a lot
