Will this cord be applicable to this garbage disposal ?
This power cord is for a refrigerator and most garbage disposals are hard wired in. You could use this cord but would have to remove the connector at the end in order to connect it. It would be recommended to hard wire the disposal if possible.
Will I get installation instructions with the power cord I need?
There are no installation instructions that come with the power cord. It is a simple repair. You will pull unit out from the wall, making sure old cord is disconnected. The lower cover of the back will need to be removed. Once removed you simple disconnect old wire from harness and plug new one in making sure that you install the ground wire.
