YA DIG

So i have a 95 s14 and the speedometer doesnt work. From previous owner he told me there isnt one, so i figured id go and buy one. Ive looked all over and seems like half the people say any s14 sensor will work then some say has to be 95 only since the plugs are different. Others say it has to match your cluster which would be 95 base model, se wouldnt work as well... So ive been looking through FS threads and craigslist and partouts EVERYWHERE and nobody seems to have a 95 speedometer. I found at autozone
PN SU5438 a 95 one, but doesnt look like any other the other speedsensors ive seen. Can somebody please put me out of this confusion please!!!!!!!
