Painless wiring starter relay

I am starting to install a painless wiring harness into a 69 cuda that is in process of being put together. The car is not going to be stock so factory appearance and workings does not matter. It looks like the instructions show how to do it without the factory starter relay on one page and then on the next page they show the factory relay. Has anyone done the install without the factory starter relay? I attached a copy of the install they show without a starter relay.
