The following is in regards to a 1998 Grand Prix GTP with Supercharger - all stock from the factory as purchased (no mods). I had some noises coming from it before a long trip and my mechanic told me it might just be best to unhook it for the time being...I didn't have the money to diagnose and repair at that time...plus I did get a little better gas mileage for my trip too!

Fast forward ~4 years and I am now getting around to hooking it back up. I am pretty handy, but this is my first time delving deeper into the automotive realm. I have a few questions but am definitely new to all of this so please bear with me

1. Are there any concerns I should have when hooking the unit back up after a long period of inactivity? (things to lube, tighten, test, etc)
2. I am unsure what was "unhooked" (I was told the belt was removed and it was disconnected from the "computer") what else needs to be plugged in besides replacing the belt, if anything?
- I have looked for electrical/wired connections that are not plugged into anything, but I cannot find any such connections.
3. If I make the assumption that all "connections are in place", and I hook the belt back up right now....start the car...if my sensors and other connections actually are NOT plugged in, will it damage the supercharger or car in any way?

My plan is to check that the supercharger is still in working order, and then replace the nose/snout, coupler, and oil. Thoughts? Suggestions? Answers to the above? I appreciate any input you experts can provide!
