Even although I am sure your experience says this and we should take note, I would still like to know WHY resistor plugs will cause an ignition module to fail.

I would also like to know more about wire/plug combinations. Bosch, who are not new at this game, say that we should use non-resistor wires 09097 and resistor plugs WR7DC+ on our early 107,s or other M117 powered cars.

Are they wrong? I have called them and the confirm their recommendation. It's hard to know who we should believe.
