neutral safety switch problem ,maybe??

okay i am starting to get confused about something i thought i was on the right track on,94 pon.grand prix(3.4) with automatic shift in floor consule, am getting a (prndl) trouble code and car has developed a syptom of engaging the key to start,but absolutly nothing till you jiggle the gear shifter around a few times(in park and neutral)then it seems to catch and start,i assumed it was the neytral/safety switch located on the trans hump that has a wire plug in and the gear shift linkage attached to the top bolt,upon talking to quite a few parts places they keep coming up with switchs on the steering column,saying the trans hump switch has quite a few plug in's and wireing harness's to it,what is going on i thought it was as simple as the switch on the trans hump with one or two plug in's and disconnection of the cable linkage,once again the car runs fine,shifts okay once in drive and it only seems dead upon staring with key engaged till you jiggle and mess with gear shifter meaning jiggling the switch till it engages(RIGHT?)what am i missing with steering switches and multiple plug in's and wirering harnesses?? bob
