I attempted the ms45.1 to ms43 swap 4/5 yrs ago on my ZHP. I had the engine harnesses, alternator, 3wire maf, o2 sensors, DME, etc etc etc...under the hood things were plug and play. Especially since I was working on the ts3 setup.
The harness for the chassis and the instrument clusters are different and I could not get far enough to get them to communicate. I even attempted to swap to an ms43 cluster but the plugs on the back were different.
I gave up because ESS was able to provide me with a ts3 tune based in the ts2+ tune using the known parameters from the ms43 ts3.
BUT.....I will say the ts3 setup on ms43 felt better/quicker and recorded better performance stats (at best as I could reproduce on the same track with similar temps)
