O.K. Bob, and Tracy thanks;
I will keep you updated as we proceed.  Looks like Tracy and I need to have a brief conversation about the EM3, and then all should be well.

Hi Greg,

I've seen some preliminary diagrams for the EM3.  It's a big
improvement over the EM2 from the connection standpoint.  There is only
one 'D' style connector.  All of the sensors are connected using
terminal strips.  The good news is you can make those connections
yourself.  The bad news is I can't do much for you on them.  It's just
a matter of stripping the wires, inserting them in the terminal strip
and tightening them down.  The one 'D' connector is similar to the EM2
P3 cable.

Re: Tracy's comment.  When doing the actual wiring, I always use the
wiring diagram and tables from the user manual for your unit.  It often
comes directly from Tracy as he can send me an electronic copy.

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.
