Zafira Starter Relay disgram?

My Vauxhall Zafira has been failing to start.
History:During summer ignition switch was sticking on which resulted in blowing out the ignition switch and starter motor, they have been replaced.
Now there is no action from turning the key in ignition switch - have had starter motor and ignition switch checked out but they are fine.
Now need to know how to check the wiring from ignition to starter motor to ensure that it is not earthing out or there is a fault somewhere in the wiring - a Starter relay diagram would be great.
