Alright, I just testeed the starter motor by the method described, it engages immediately when power is applied to the middle male connector. I guess that pretty much leaves me with the NSS.

Q: When I shorted pins 30 and 87 on the K38 (starter alarm relay behind the instrument cluster) it appears that I also bypassed the NSS according to the ignition schematic that I have attached. Is this correct? If so, it pretty much points to the NSS being the only thing left to be bad.

Q2: Is it "ok" or safe to drive around with the pins on the K38 relay shorted? The e320 is my only transportation and the city bus/cabs are getting awfully annoying.

Thanks again! I'm sure I'll have more questions about the install of the NSS if that ends up being the problem.
