Fuel pump cut switch 87TII

I did a search and found a message to run a switch off the ground wire off the main FP relay. I did this and when i shut the switch off the car remains running. If I disconnect the relay it of course shuts off.

Why does this not work? Should I use a different 12V wire? And if so what amperage of switch should I go to?

Thats all, thanks.
Terry

The main relay is under the dash by the steering colum. Switching off the ground wire does not work. I just got back from Radio Shack and am going to use the blue/red wire with a 25amp switch. This is how ReTed has his wired. He beleives that you can do it by switching off the ground, but it does not, I proved it.
Thanks
I will post back if it works or not.
