4th dash swap.. PLEASE HELP

i'm buying a 93 Firebird dash... i have a stock v6 camaro with the 700R4 tranny... what all do i need to get the dash working properly...
i'm getting the dashboard, console, gauges and cluster and wiring harnesses..
now the real questions are..

1) the little yellow box, thats the speed sensor correct? i've been told i need to get a new one, anywhere from like 91-92yr camaro..

2) do i need a dakota digital box? aren't these for digital readout dashes? do the 93 firebird dashes even have anything digital on em?



i'm hoping to buy this tomorrow, so any quick input would be great... thanks..

oh for those wondering, i have a 3rd generation camaro thats mechanically driven by cable, the newer dash is electrical..
