Has anyone installed and used HR9DCs in place of the non-resistor H9DCs? I'm having a hard time finding non-resistor plugs to put in my M103 (even the local parts store doesn't seem to have non-resistor plugs in stock), and I'm wondering if anyone has any operational experience with these.

Thanks,
Anthony

Have you tried calling your Mercedes Dealer? I got mine from Caliber motors Mercedes-Benz. You might try Phil at fast lane.
