Default New PA Alternator

Well, breathing a bit easier now. I had read some posts saying that PA Alternators had arrived from American Muscle beat up pretty badly and damaged in shipping. Mine just showed up and it was in perfect condition. Whew!

Now, here's a couple of questions for those that have possibly been this way before. 07BLACKGT talked about his new alternator not having a clutch pulley as the OE one did. Should I consider taking the clutch pulley off my old alternator and swapping it onto the new one? Would it be worth it?
Second, I also purchased the upgraded power wire from AM. Where does this wire go? Sorry, but my car is in the detail shop and I can't just run out and look at it. Man, this is a serious hunk of wire.
I'm sure I will figure all this out, but a little direction from somebody who has done this never hurts.
Thanks in advance.

Man I really hope all works out well for you. My alternator (which was chrome) came nicely boxed up also. Once they installed it, the guys at the shop notified me that it was overcharging. I was just surprised and upset at how PA performance handled the issue that I had. I'm pretty sure you'll be fine though. GL!

The upgraded power wire should connect from the B+ terminal on the alternator to the battery. The OEM wire should be the thick cable on top of the passenger side fuel rail:

Yes, swap the clutch pulley from your original alternator.

Any trick to removing the clutch pulley?

Can I use my new PA alternator (non-clutch pulley) as is, or do I have to put a clutch pulley on it before I install it?

There are tools for these pulleys; search for "alternator decoupler pulley tool." It looks like PA sells one for $19.

Doesn't PA recommend using both the stock wire and their wire together?

Default Performance Power Wire

I called both PA and American Muscle. PA said they recommend using both wires, American Muscle said to just use the performance wire. Great. That really clears things up.

It can't hurt to use both wires, you'll effectively have one very thick gauge wire.
