Kokid... I did this exact swap myself. It is pretty easy and straight forward. I looked around for a head unit aka deck and then started my price research. I found Ebay to be the cheapest route. You can pick up a connector from your local auto parts stores to connect directly to the factory harness w/o cutting your car wires. Also you can get a universal mounting kit for it.
Connector is probably about $8, mounting kit could be up to $20. If you wanted to retain steering wheel controls you would add a PAC SWI at about $50-65
I documented most of my process here when I put this stereo into my 95 with gain slider.
Then I moved it into my 97 here
The only real thing about the 97 to keep in mind is there are two connectors on the back of our head units. One is the main connector and the second is a single orange wire for power to the bose system.
Please ask any questions you have...
