I installed a back splash on my 177se.

When doing the install i removed the light switch, heater switch, and the range hood..

I got everything back together and working except the water heater switch and light.

I have 4 wire connections.
Yellow wire solo.
Orange wire solo.
2 green wires in one connector. 
3 white wires in one connector.

I failed to take a picture before removal..  FB_IMG_1503805087239-600x800.jpg  FB_IMG_1503805780825-600x800.jpg

The silver spades are to the light

Below is how it's wired. If I were to guess, the white wires are ground and go to one connection on the light. Green wires +12 to one side of the switch. You should be able to check that with a meter. For the other two, I'd look at the wiring at the water heater itself, under the driver side dinette seat.
