Hi Shane,

All you have to do is connect the two batteries positive cables to the inputs of the battery switch, there will then be one outlet, directed either from battery 1, battery 2 or both.

It is ONLY the positive cables from the batterues that we are concerned with.

What about the common ground slot on the switch?

the common runs to the starter; both +'s run to the switch then run the common to the starter.Then ground both batterys to the motor. I think thats how its done someone let me know if im wrong. thanks
