Honestly, it was a bit tricky, considering neither of us had ever done this level of wiring for a car, but once you start tearing into it, it's not that bad.

The main thing that made it difficult was that there was next to no information available for the Maserati engine wiring. So we'd have 3 or 4 wires coming out of a connector, and no idea what was what. "Black is ground, okay that's easy. Now this red one is most likely power, probably 5v. So what are these other two? Signal in and signal out? Which is which?" Stuff like that. Even the local Maserati/Ferrari dealership didn't have half the informtion we needed. So we did a lot of stuff from scratch or with extensive sleuthing that wouldn't be necessary on any other engine with marginally more support available.

On Haltech's side, however, everything is fantastic. The ECU and wiring harness come out of the box with labels on each wire, and a full fold-out diagram of what wire needs to go where. I wouldn't hesitate to use Haltech again, and on an engine with wiring diagrams available, it would be trivial to do. And Haltech makes pre-made wiring harnesses for most popular engines, making it literally plug-n-play.
