Default MS2 for an MSM engine in a 99 - Halp!

Ok, I am a bit confused..... Ok a LOT confused. I have searched, googled and questioned.. But I am just getting more confused from the conflicting answers I am finding. So I am hoping one of you all can give me a solid definite answer.

I have a DIYPNP MS2 kit for a 99-00. I am going to use it to run a 2004 Mazdaspeed motor and stock turbo setup. I plan to use the 99 Intake for the VICs, a 99 engine harness and the MSM factory coils.

Exactly what all mods do I need to do?
These are the assembly instructions I am following currently.

Please and thank you very much!

mods to what? the megasquirt? why would you need to mod the megasquirt? as far as it knows, it's controlling a 99 engine

Well, as I understand... There are a few mods that have to be done to it , for it to control a 99 engine. But I am not 100% sure of what all those are. It looks like I have to build a circuit for the Alternator. That one seems to be universally agreed upon. Also, It seems like there is something I have to do for it to control the AC and the VICs? And I am not honestly sure what else.

So rather than continuing to sift thru old documents and conflicting info, I figured I would ask the experts on here for a definitive answer.

is it a pnp unit or isn't it? you're so confused you're confusing me.
if it's a unit for 99-00, that already worked on a 99-00, and you're installing it into a 99-00, and just using the msm long block it should work (after you figure out the coil pack vs cop wiring)

It is the DIYPNP Kit... This one to be exact.
DIYPNP Nippon Denso 76pin Unassembled Kit DIYAutoTune.com

So I am in the process of building it. Actually I am just about finished with the initial build.

*Edit*
I just realized I guess I put this in the wrong section.

i think he was referring to the engine harness in the engine bay. you will need the engine harness from a 99 and use the 99 sensors and wire in what you need to control the MSM engine.

ok let's get this straight:
-you have a 99-00 pnp ms
-you have a 99-00 car with original harness
-you want to use both the above to control a MSM long block
......sound about right?

so the only modification, if any (and this part someone else will need to confirm), will need to be to get the 99-00 ms to run the 01-05 COPS.

Why? It should already have the alternator set up, and there's no difference between alternators in 99+
I already told you this in the other thread

Diypnp themselves said I have to build the alternator circuit in the proto area. The ms2 doesn't have the ability to control it, built in. Be it a 99-00 or an 01-05.

I think the biggest source of confusion is that you're posting about a DIYPNP in the MSPNP forum - the two are somewhat different critters. And you are getting responses that are appropriate for an MSPNP, but not a DIYPNP.

Sounds complicated. Use a 94-97 alternator.

Yea I realized I posted this in the wrong sub-forum.. But it was too late.
Thanks. I SEEM to have figured out everything I need. But I sure wish I could find a picture of the circuit built... Rather than just the schematic. I can read a schematic.. but have a hard time visualizing them properly.

Ahh, well now I understand the confusion: I kept thinking pnp which requires nothing except plugging in and tuning, and you've got a non pnp unit that requires wiring in and building extra boards to control stuff like the alt.
