This is how the power is connected:
KL30=constant power
KL31=ground

so in my situation/application, which wire is the KL30 and which one is KL31

i have a BROWN wire as well as a PURPLE wire which i assume they to to that black 2 pin connector, but i don't know which wire goes to which pin

and then i have green with a black stripe wire that has a metal pin crimped to it and i DON"T know where that one goes either

thanks.
