i am trying to hook up a electrical cord to my dryer i recently got. it is the original plug wire that came with it but the last owner took it off and replaced it because it did not fit her outlet, now the job of switching it back out for the original falls to me. within the cord there are 4 wires, Black, green, red, and white. the black, green and red wire hook up easily because they are color coordinated, but i cant figure out where the white wire hooks up. the only other place i see that has i wire hooked to it is where a green ground wire is is grounded to the left of the terminal block. please someone help me with figuring out where the white wire hooks up at... thanks
