I can confirm later cars had a harness revision, I will likely go crazy trying to find that PDF but when I do I will edit this post. It's not obvious but the later 2015's have twisted pairs under more plastic cable rather than the varying degrees of hasty taped bundles of earlier cars. Then, as of maybe 2017/2018, the shield/cover solution was added, slowly retro fitted to earlier models that came fourth via TSB/service. From what I've gleaned years ago when my TCU failed, it tells a story of how the factory learned chassis lessons, when paired with the 8c's story, and even the Maserati Granturismo, becomes crystal clear. Reading through your bulletin brought back whatever memory on how I feel the factory engineers made lemonade from the lemons the executives and bean counters threw at them to resolve. The 4c story is as organic as the car! What's funny is there seems to be a serious team/brain change from the Enzo/MC12 to the 8C, where the "MCS" ended up tested even by Schumacher to death, while the 8C was more "Granturismo Bodykit" (but still very much it's own car versus the larger, heavier Granturismo), and then the 4c being 8c habits passed unto a midengine carbotub Frankenstein.
If the 4C had the resources the MC12 had (and Schumi to beat out the proverbial slag), it would have driven more like it looks, punching unrealistically above it's weight, and likely costing a little more, maybe a $75k+ msrp for the coupe. Just a fun feel on alternative history. Now those characteristics are up to us, which if enthusiastic, is a pleasure to take the final yard. For all the complaining that can be hurled at the 4c we got, it can be silver lined by seeing it as a discount to tune to one's own final finish rather than the factory's... And that's pretty cool in an era where the chauffeured government has more say in what a car is than a tenant and mastered automobile manufacturer.🍀
Now... Anyone down for a group consignment of a Rywire mil-spec harness and Motec processor swap?🤣
