I have an 05 sr5 4x4. I left my key on accessories and my battery died overnight. Grabbed a battery I had laying around, slapped it in with the cables on backwards, like a fool I know. Anyway, it'll start and run, but nothing else works. All accessories are dead and all the lights on the dash are on. It'll rev to 1500 rpms but nothing more and will not shift into gear. Any ideas or suggestions?
