Hi: If you look at the pics below, I included the entire system wiring schematic. Take a look through it and let me know if that is what you needed.

The schematic was two pages long. I had to cut each in half to make them readable for you. I did overlap them so you can follow from one to the next.

Here is a link you may find helpful when checking wiring.

Let me know if this helps or if you have other questions.

Take care,

Joe
