Thanks Bob;
Willdo.  I have the EC3, and plan on buying the EM3 whenever Tracy makes it 
available, so I will need wiring for both.  Additionally, I will need some 
input on my 100 amp alternator (side mounted) and a 2-battery system, with 2 
separate busses.  I also want a separate ground switch to power up the 
GPS/EFIS, so that I can program them without the engine running, while I am 
parked, for safety purposes.  Any help you can give me on this is 
appreciated.
Greg Ward
