FUEL PUMP RELAY PROBLEM.....PLEASE HELP!!!!1983 500sl Euro

I Replaced The Relay Because No Power To The Fuel Pump....

The 7 Pins On The Relay Have 2 That Are Getting Power And When I Turn The Key It Does Not Click Or Make Any Noise...

Could There Be An Ignition Switch Or Somthing That Is Supposed To Activate The Relay....

If So Where Is It Located So I Can Test Or Replace??????
