Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
Can you get us the full model number so I can see if I can pull up the wiring diagrams for this, now you say you have two extra wires coming from the stove itself? And there are two extra connectors on the board? Is that correct?
click this link wiring the wiring sheet should come up. I took a look at the clock or the control but it's small and I can't really see what's there, what you need to do I know to the green wire is definitely a ground wire which will probably be connected to the control metal body, take a look at the wiring diagram and tell me what you think about where these wires may connect, they have done retrofit kits on these and that's probably why there is a difference in the wiring sometimes you don't need them all but we have to make sure, let me know what you think when you look at the wiring diagrams.
