I'd do a continuity check with a DMM to ensure the wires you think are the right ones near the ECM relate to the right pins near the injection pump harness connector.
I'd use a switch only because the ECU probably checks the impedance of this circuit when you first turn the key...if the impedance is off, it might throw a code. The reason I feel this way is this is exactly how the "ALH" vintage VW TDI's operate. Flip the switch after the engine is started...or while out on the open roads and you won't have any issues.
This mod on the Merc's is analogous to the "Evry mod" on those TDI's...just fooling the ECM into driving that circuit harder to move the rack in the right direction for more fuel. Idle stability suffered in a big way with the TDI's as you reach the ragged edge of adding more resistance...I'm unsure what will happen with the Merc's...
Cheers,
Matt
