Relay's included, but the wiring is not what I thought, if I had connected to what I had show before I would have reversed the fuel and 12v- connection's. The picture of the back of the 5 pin ATS connection's we can see some of the numbers.
Red cable Pin 1, 12v pos
Yellow cable Pin 2, Crank
Orange cable Pin 3, I believe to be the start Relay
Green cable (it looks blue in the picture) Pin 4, Fuel
Black cable Pin 5, 12v neg.
I have now found the on-line manual for the smartgen controller and a few youtube vids as well.
