Well most of the wiring underneath my hood is cleaned up already. My battery is relocated in the back and that gave me much more room. What is nice (depending who you talk to about MAP vs MAS) is that I don't have to mess with a MAS sensor. I have the MAF-T sensor but that is coming out and I am just putting in a section to replace that. In the replacement section is where I am placing the GM IAT sensor. Should be close enough to the intake to get a fairly good reading.
I am going to try to get a good tune on it first by the instructions. Someone on the msextra is going to give me a starter MSQ file that should be simmilar to what I will be running but there is always differences between engine and it would have to be finer tuned. There is a software program that will look at the data on a given run and suggest changes that can be made to the tune. I am more interested in tuning it my self but if it gets too overwelming I will probably take it to a tuner. However all the instructions are very well laid out to tune it. It really shouldn't be that big of a problem.

I don't know when you bought yours but I think it can support it now. I think it is in testing yet but here is how to take over ignition

It wasn't long ago that MSII could be run on dsm and it still in testing.
To my surprise is that the modifications to the MS board is very different from MSI to MSII for the DSM. So if you think about just changing the chips, it will probably cause problems. The instructions are fresh for the DSM 4g63 but later I want to post a how to that will simplify the instructions.
For the harness what I am going to try to do is find a bad ECU and take the clips off of it to plug into the stock harness. From there just match wires from ECU to sensors. I figure if I didn't like the system or if I have a problem, I can always switch back.
Something kind of sexy about this system is the flex fuel sensor option

To sum it up short, a flex fuel sensor can be used to determine the ratio of ethanol to gas and compensations can be made. Think about that, have the option of putting E-85 one day and Regular unleaded fuel the next day
