cheapest way to get hemi 3g going?

Ok, so now that mopar has agreed and stepped up to help us all out with swaps. I see that they have a complete stand alone engine kit for 6k...not happening.

I already have the engine. I need a wire harness, and ecu. then i can at least fire the engine and make sure it works...i can deal w the cable and stuff later.

Ma' Mopar has a wire harness for $700.
Hotwire Auto's harness cost $1000
then you gotta buy a computer, the fully programmable from Ma'Mopar is $2200.
Hotwire will flash one for $700, less if you buy their harness.

then there is all the extras, throttle body, pedal, etc etc.

so what is the cheapest route?
and making my own harness is not an option, not with out a full work up. step by step.
