Just need a little direction in removing the alternator from my '99 zr2

[Chris '99zr2]

Hello... I'm new to the forum. I spent some time moving around the site, reading the threads and I gotta' tell ya'... this is the best forum going.
Okay, I know I should be able to figure this one out... but looking at the serpentine belt, the tensioner, the idler pulley, and that over-the-top bracket... what the hell!?!?
Anyway... I just wanted to know the right way to remove the alt from my '99 zr2 extra-cab with the 4.3 and auto tranny. I have to swap it out 'cause she's a little tired.
Go easy on me... I know you're all laughing at me for not knowing this one. Most of you guys could probably do this in your sleep, right?
Thanks in advance for the help.

First step is to remove the neg. battery cable to keep from shorting out anything.
Then figure out your tightner pulley and get the belt off.
The alternator should have one bolt on power feed wire and a plug in for the other wires.
The alternator is just unbolt and bolt back on deal.
You should have a belt routing diagram under the hoood for belt routing.
If not draw one out or take a picture of it before taking the belt off
Good luck
