Yes, the wiring is correct there. Sorry for the confusion.
And as far as strapping, yes it's beneficial to the meter or RTA, but not really to the ear. As long as you tune both with an o-scope, then turn the higher one down to gain match with a DMM, you'll be fine.
If all you're using is a DMM, then use manufacturer recommendations. You won't be getting full potential, but it will be clean.
