I just removed the oil injection from my '95 Mariner 200 EFI, and removed the warning module on the top rear of the motor. Another module was stacked on top of the warning module, I assume it's the detonation module. The two modules were separated by a metal plate and some small spacers. My question is, now that I've removed the oil warning module, is there any need for the metal plate and spacers that separated them? Thanks
