how to wire a flavel 100 regulator switch?

my pal has a Flavel 100 AP10FRK, his oven regulator switch broke, as a temporary measure he decided to swap the grill switch for the oven switch. he took photos and unpluged the wires but the camera wiped the photo of the grill switch and the only wiring diagram i can find has no wire colors. there is a red, orange, white, white and grey and a yellow and orange. what terminals do they attach to, please help.
