I am installing a dishwasher. I bought a pigtail that is all gray in color, flat cable with 3 wire and plug connected. It is a GE plug for dishwasher hookup.
I know the green wire goes to ground on the dishwasher. The other two wires are both copper in color. And the housing is gray. The difference is that one wire has groves on the coating and the other does not. Which one goes to the Black wire on the dishwasher and which one goes to the White wire on the dishwasher?
