Ez track turnout - spur line

[Alez]

New to DC HO Track wiring.

I have two spur lines with metal frog turnouts, both are going to be used for parking locomotives in my layout.

How do I wire a #4 EZ track turnout with a metal frog to work as a spur lane to park trains?
Is the wiring different from a turnout with a plastic frog?

Any help would be appreciated.
Thanks

Isolate the spur tracks at the turnout. Wire the spurs seperately and include a manual electrical switch to turn the spur on or off.
