Re: Please help!!!
It's a 4.6 if it's original. Owner's manual should give you the fuse identification, but I think it'd be for the convertible top, if yours was a convertible. The missing wire looks like it might be for your temp sensor, but I'm not wholly sure about that. The radiator cap shouldn't have an affect, but if the pressure the cap is designed for is too low, it will lift and you may run high temps. Not enough info on the AC, may have lost it's charge.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
