Spread over three days I figured out how to wire up the Engine and made some progress roughing in the installation. I decide to install the Regulator under the Coolant Bottle, on top of the Root Tube, and the Engine Ground Terminal Strip ahead of it, under the Radiator. The Rotax installation manual and a CD I purchased from Aircraft Spruce (www.HomebuiltHELP.com) were valuable in understanding what is needed here. So I have the Cylinder Head Temperature (CHT), Oil Temperature, Oil Pressure Switch (Hobbs), the Regulator, the Engine Ground, the Electric Tachometer and the Starter hooked up now. For the wires to the Ignition Modules I am waiting for two special flat pin connectors and grommets that the rebuilt engine supplier (Rotech Research) are mailing me. 23 July 2016 update: installed. I decide to use a tapped hole in the front of the Reduction Unit for the Engine Ground. This requires a M6-1.0x16mm Hex CapScrew with a toothed lock washer.
