Need help wiring a delay box..........

Backwards! I need it to put out 12v when the timer goes off
Can this be done?
I drag race slot cars and Im looking to hook a delay box to my controller, when the delay box timer counts down I need power supplied to my controller
Anybody have any ideas?
Thanks

Just use a relay. send 12v power into 30 and 85,hook 87 to youre controller and 86 to the delay box.
