07 mastiff - ignition module wiring / replace /rewire ?

[hayseed]

hello,,, i am in the process of swapping motors and am trying to trace back the wires from the stock thunderheart to map to the new setup -- 3 groups of wires coming out,, one set goes to the coil, one set goes to the crank sensor, and one set loops into the EHC (correct me if i am wrong) -- the new motor (have not recieved it yet) will have the ignition module self contained in the nose cone -- so i am wondering how to wire the ignition switch and still use the EHC module for that if possible or am i going to have to rewire the whole thing ?
coil wires to coils wires...
crank sensor to crank sensor if applicable
then i am a little lost

i am answering my own qyestion here -- looks like the 3rd group of wires is power/gnd/tach signal,, the wire diagram shows a second "optional tach port" connection,,, anyone know what that is for ? my thoughts are to run the power/gnd = and tach through the ehc and the other wires to the approprate coil,,, looks like it should be "easy" -- thoughts?
