05pnygt

so i recently sold my 05 gt and got a 96 gt and the speedo and tach don't work.... i already had my mechanic check the speed sensor that's fine.. he said it's either the gauges or the pcm that's causing this to happen so i have a new cluster coming my question is if the new cluster doesn't fix the problem can i get a programmer like sct livewire or something to show me my speed and tach readings?


thanks for your help..
