Need a simple schematic of a time delay for a 12Volt relais

That won't work.

How do you want it to work- delay relay closure or opening or both? Delay starting when switch closes, opens, or when 12V supply is applied? How long do you want the delay to be?

When I'm applying power it need to close between 5 and 10 sec.
What about this one or do you've one yourself?

Download the datasheet and design one. It's very easy.
Just add a power supply and a transistor to drive the relay.

Difficult, then google for it.
