Airbag and Cruise Hookup...Please Help

Please help, i have a 01 v6...i just bought it and the cruise control harness behind the steering wheel was unplugged....i bought the car with a reconstructed title....it has moderate front end damage...would it be safe to plug this back in or where could i locate the airbag sensors just in case?

Maybe

My cruise control doesnt work, my passenger side airbag has been deployed...and im pretty sure the steering wheel airbag has been replaced because it is off color with the rest of the wheel (Darker Gray)...the harness seems to lead to both the CC and the airbag attached to the wheel assembly...im completely clueless...i recently checked the 2 sensors i was able to locate behind the pony emblems on the fenders and the results being: the passenger fender sensor was missing and the drivers sensor still in tact...it was hit on the passenger side bumper, the person i bought it from told me he hit a curb (Although i was told when taking it for inspection that there was moderate frame damage)...i have no clue where to go from here, recently i took it out and it had a sputter when i gave it alot of gas (Past 3000 RPM's) and it got to the point when i gave it gas it wouldnt gain speed. i shut off the car and turned
it back on and it gave a little help (Would actually go up to speed) but it still sputtered. After i gave it about two days rest it acted normal again, but as soon as i gave it hell it started doing it again....Please any feedback would be greatly appreciated...im about to take a 500 mile trip and im hoping to fix the issue beforehand...
