Power Wire Upgrade w/ Alternator Install

Hey all,
I installed an aftermarket alternator tonight and I had some questions. The alternator is made by OE Plus ( www.oeplus.com ) and it's a 100 amp alt. I bought the PA Performance Power Wire Upgrade Kit as well. We tried to find a place for the Power Wire Kit to hook to the alternator but it was just a clip sort of.. there wasn't a place to hook into the alternator. Now i'm almost positive that you have to upgrade the power wire when you upgrade the alt. amperage. I was just confused as to why the PA Performance kit wouldn't work.. the only reason I could think of was that the alternator wasn't made by PA Performance. The Alternator I bought came with a paper that said "Every time a Ford IAR alternator is replaced, a new alternator-to-wiring harness plug must be used." Is that like the same thing as the Power Wire Kit? I'm just confused as to where to connect the Power wire on the alternator... If the alternator will be ok without the power wire upgrade kit.. then i have less worrying to do. I just wanna make sure everything is safe- if anyone can tell me where to hook the power wire to the alternator.. or if it's not even needed, that would be great, thanks!

I'm sure that's probably it.. probably not a 3G unit. Sorry! So the PA Performance kit won't work.. and I have to get some other upgrade? Or is it going to be fine without the upgrade?

Well.. no I was an idiot and installed it already.. soo looks like i'm gonna go with option one.. as long as it is safe. All the connections were the same.. the only difference is the new one was like 180 degrees opposite of the stock one.. actually it wasn't stock it was a ford motorcraft remanufactured one which i didn't realize. I bought it at salvo auto parts, the guy told me it was 100 amps so I'm pretty sure it's 100A. Thanks for your help.. i just wanna be safe.
