Having swapped a 3.2 into my '76, I'll throw in my two pfennig. Interfacing the "brain" with the rest of the car isn't that difficult, really. All you really need to do is get a couple of 12V power sources (from your fuseblock) to the DME/DME relay. The DME really only connects to existing components on the engine itself and not so much into the rest of the car (aside from the above mentioned power needs and a connection to a tach).

What you will have to sort out is supplying fuel to the engine (not a huge deal, really) and sorting out the wiring from the engine that controls the starter and all of the signals from the various sending units. Porsche seemed to be relatively consistent on wiring of gauges, etc., over the years, so this is also not a *huge* task.

My advice would be to gain a good understanding of what connections exist on the 3.2 (gauges, power, tach, starter, etc) and then figure out the best way to interface them with your particular car. In the end, it's probably not going to be as bad as you think.
