Since a relay is a pretty simple electrical switch that uses a small current to close a larger circuit [ie starter solenoid] how about just finding an off the shelf relay that has the same values for both the low circuit and the high power circuit? I wager the glow plugs don't care as long as they get the right volume of energy when you close the switch to energize the "solenoid" that powers them. Buy one that doesn't say "Mercedes" on the box, but works the same.
