I don't know if you're still having problems with your relay, this thread is kinda old.
You're describing the "auxiliary relay panel." I've got an '87 325 6cyl (didn't check what you're running) and on mine, the one closest to the front of the car is the main relay. In line they are 1.main relay, 2.fuel pump relay, 3.oxygen sensor heater relay.
