On my LSA, I used the GMPP #19259293 engine controller kit which included the engine harness, fuse box, 02 sensors and bungs, MAF sensor and mount and a pre-programmed PCM/ECU.

It was all plug and play and the fuse box came pre-wired with relays for the cooling fan and fuel pump(s). Just needed to wire up a reverse solenoid lockout controller kit that I bought from Modern Driveline in the states, and it all started and ran perfectly first time.

I used the OEM GM LS3/HSV cats (modified to fit my Pace Cobra) for the IM240 emissions test and it passed with only a minor tweaking of the tune. Given my motor is supercharged and puts out greater emissions, a NA LS3 would romp it through.
