Hob wires

Can anyone tell we the back wires are for and what they should be connected to? Everything appears to be going somewhere except the two rolled up.

 

Has the hob got an ignitor button?

 

Thanks for the reply - instructions were not that clear to me initially - make sense now it's just the 12v power and earth. Was just concerned I was missing something. Switch is incorporated in the gas button.

 

I'm no expert in fitting hobs btw, but it makes sense that if you have electric ignition it's going to need some sort of supply

 

There was no obvious ignition button - so was thinking something was missing
