Hi, My Toyota dealer took my hybrid battery apart and said it couldn't be fixed. I got the car back disassembled to give it a try myself. I cleaned all the corroded parts and puzzled it back together, and have one white wire connector end and don't know where it goes. Maybe it's for diagnostics? and doesn't go anywhere? Please see picture and let me know what you think. I looked at a bunch of on-line YouTube videos, but they were for a 2007 and I didn't see my extra wire connector. Ok... thanks!.
