Has anyone successfully used the USCartool A500 Crossmember?

Well, these showed up today in the mail.
I will mount these in my console, and use them to turn on and of the overdrive and lockup.
These have two lights in them so the text will be lit whenever the car is running, or may hook it to the lightswitch, and the symbol at the top will light when the switch is turned on.
Had the switch covers custom laser etched to read Overdrive, and Lockup
