Since Hotpoint is a GE and GE likes to keep their tech info a secret I cannot be of much help.

Have you checked in the control console, they like to store it in there sometimes or taped to the back panel.

Here is a good link, they do have some example wiring diagrams for GE which may help some.

Check out #28.

Hopefully someone else will jump in with the correct diagram.
