[Supras] Strange AEM EMS activity

[Brandon]

exactly, it just cycles the pump on and off in rhythem but only when the AEM 
is grounded.  For right now i just used nylon washers and spacers to isolate 
the EMS.  I would be fine w/ this for a solution, but i'm afraid there is 
going to be another part to this that rears its head later on.
