alternator install?

First, disconnect the negative battery terminal just to be safe. Then you need to remove the belt. Put a rachet and socket on the belt tensioner pulley and remove the belt. Then jack up the car (alt is on the bottom of the drivers side if you didn't already know) and there are 3 bolts you need to remove, maybe 4 if I remember correctly. Once you remove them you can pull the alt out, just disconnect the 2 wires in the back and you're done. Installation is the reverse.

Disconnect the battery. If not, you'll get a spark show like me
Three bolts hold it in. Two are plainly obvious, and you'll see them as you look at the alternator from the front of the car. There is a third that comes in from the opposite direction, and is a much shorter bolt, towards the top of the alternator. There is a nut that holds one of the wires on. That's the easy wire. There is also a wire that goes into the top of the black plastic piece on the back of the alternator, held in place by a weatherpack connector. You'll need to unclip it, just like you would any of your other weatherpack connectors. This is the wire to watch out for, as it is small, and can easily break.
Once the three bolts are out, and the two wires are disconnected, you can safely remove the alternator. It might be a little tight, so you might need a flathead screwdriver to do some prying. You'll also have to do some manuevering to get it around the sway bar.
Not a terrible job, but can be frustrating.

MeentSS02 I think I might have damaged my weatherpack wire during the last install, any idea what that does? Hopefull it sends a signal to my guage cluster, my volt readings have been low ever since. And they vary10-13volts. Even at 10volts the lights don't dim with the stereo on full blast,

Removal Procedure
Caution
Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.
Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure .
Remove the accessory drive belt. Refer to Drive Belt Replacement - Accessory in Engine Mechanical - 5.7L.
Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
Remove the positive cable from the generator:
Slide the boot back along the cable.
Remove the positive cable nut (at generator).
Remove the positive cable from the stud.

Disconnect the generator electrical connector (3).
Remove the generator.
Installation Procedure
Install the generator.

Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Install the generator front mounting bolts and oil cooler clip. Tighten
Tighten the generator mounting bolts to 50 N·m (37 lb ft).
Install the transmission oil cooler lines to the oil cooler clip.
Install the generator rear mounting bolt (1) (at generator). Tighten
Tighten the generator rear mounting bolt (at generator) to 25 N·m (18 lb ft).
Install the positive cable to the generator:
Install the positive cable to the stud.
Install the positive cable nut (at generator). Tighten
Tighten the positive cable nut (at generator) to 22 N·m (16 lb ft).
Slide the boot over the generator stud.
Lower the vehicle.
Install the accessory drive belt. Refer to Drive Belt Replacement - Accessory in Engine Mechanical - 5.7L.
Connect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure .

With how small that wire is, I'd say your guess about it sending a signal is probably a pretty good one. But in all honesty, I know not what this wire does

What kind of alternator did you get. If you got an aftermarket high output alternator you may need to have someone bump your idle up a bit. If you hold the gas at about 1000 rpm's does your idle stay stable?

You should be seeing 13v+ at all times when the car is running, unless you have a lot of accessories running at idle or something (A/C, headlights, rear defroster, etc.).
