i'm guessing you'll need a Toyota brand from eBay to plug into the radio wiring. If you find one, don't make the mistake I did - installing the CD on top because I thought I'd use it more - that blocks the cooling holes on the radio - ask me how I know. Was able to find a replacement for something like $5 by searching the internet by the model number of the old radio. Got in a bidding war and paid a lot more for the original cd unit, but wanted original appearance and I've pleased with it, though now I sometimes have to insert a cd a couple of times before it works (and yes I have run a cleaning disk) The alternate is to just buy a newer radio and cd combination and also buy the wiring connectors so you con't have to cut anything.
