I believe that all non jbl toyota use the same connectors since 87. So electrically should work. fitting it in may be tougher. If you have the radio from the scion or can get it for free or near free, and are willing to make mods, then go for it. It the radio is going to cost almost as much as an aftermarket radio then why bother.
I do have coming adapters for both sides for my tundra as I am doing a speaker level input and did not want to cut factory wiring so they are available
