 12 volt plug in the back and then this was interesting control you pushed it I didn't quite know what it was right away but actually it is a swing out bicycle rack mounting system you can't tow with it but oddly it did have a tow connector on it so I guess maybe for a light or something like that but it swings away and you don't see it spare tire on kind of a strange looking wheel but nice to know it's there as I say under hood
