Construct Armor Clarification

[AdamMeyers]

I find myself in a position in a campaign to create a construct for my character and outfit it with the construct armor modification. Sounds great, but I'm a little confused on some points.

It says my character keeps his BAB and saving throws, and that the construct counts as wearing a breastplate as far as the AC, max Dex bonus, spell failure, etc goes. So does that mean I also keep my own stats, or do I use the construct's stats? I assume I keep its Damage Resistance and special abilities, right?

Really, my biggest question is about the physical stats. The fact that I'm piloting the construct and the wording that I only keep my own BAB and saves seems to tell me that I use the constructs Strength and Dex scores, but that seems to be counter to the statement that the construct counts as a breastplate for ac and Dex. After all, if I use the construct's stats, then I'd just use its natural armor and Dexterity score, right? But if wearing a construct just counts as me being me but with a breastplate on, then why do I (I assume) get to keep all its attacks and special abilities, and gain its HP to protect my own?

Those two points make it sound like I'd use the construct's Strength, attacks, and DR, but use my own AC and Dex, but that certainly isn't declared in the rules.

I'm just confused on how construct armor actually works. I'd be grateful to anyone who can help explain it to me.

For reference: Building and Modifying Constructs.

This is pretty poorly explained, I feel. It seems as if the character controls the construct (as a sort of mech armor), so you'd use its statistics for everything except the specified exceptions. (BAB, base saves, AC, spell failure).

I don't know if that's what's intended, though.

When I think of people wearing constructs in a fantasy setting, I think of "Visions of Escaflowne"- two warriors piloting giant robots in epic sword battles. However, according to the rules:

Only the creator of a construct can wear it,

The construct must be the same size as the wearer,

The construct only grants an ac bonus equivalent to wearing a breastplate,

And my original confusion, about whether or not you use the construct's stats, speed, natural armor bonus, etc, given that "you only retain your own BAB and saves" seems to imply you do, but " wearing a construct is the same as wearing a breastplate" seems to imply you don't.

I believe that you only treat the construct as breastplate for determining armor proficiency (medium in this case), Max Dex bonus, armor penalty and arcane spall failure. I could be wrong, but if you're supposed to use it as breastplate for anything else, there doesn't seem to be much point of wearing it. And for a bigger construct just add a way to automatically Enlarge Person the pilot while it's being worn.
