In the Kit of parts that you get, there are couplers for the window motors that allows you to drive a shaft with it. I think because of the coupler, it can only work with one of the two window motors...I think because one of them had like, a 9 tooth gear on it and the other had I believe an 8 tooth gear. I may be wrong about that, but ya, they're in the kit. Good luck with that for how you're going to use them. The possibilities are endless.
