How do you replace the larger red wire on an alternator for a 97 Sunfire and what is it connected to?

That would be the battery wire. On some cars it goes over to a junction block on the firewall/fender, and on other cars it goes down to the starter. Disconnect the battery, as it is a live wire. If the wire is now too short to reach the alternator, take a peice of it with you to an auto parts store and ask them for wire and terminals, as well as a crimper tool to repair the wire. This method will cost a little bit of money, but it will be cheaper, and less aggravating than buying a replacement wire, and running it through the car's harness.

To change the alternator in the truck, first disconnect the battery and then disconnect a plug that the alternator has on the right top of the alternator. Then there is a red cover that has a bolt and then unscrew that and then there are two more larger bolt, one on top and one on the bottom and then it should come out. But before you do all that take off the belt. Thank you

Remove the negative from the battery. Use a breaker bar or larger ratchet to turn the tensioner. This will loosen the serpentine belt for removal. Disconnect the wiring harness from the alternator, loosen and remove bolts holding the alternator then remove it. Place the new alternator in position and follow the above steps in reverse.
