Hey Guys! Im kinda new, I posted a thread with kinda of a noobish question and got no results. Been lurking the last 3 years since I had no car

Im basically going to copy past it here but TLDR version is, im picking up my first car this weekend, everything runs great and is a KA-T but only issue is open downpipe lol which is loud as f*** and the speedo doesnt work.
Are there any ways to check to see if my VSS is finished or multimeter test my speedo for anything? The guy told me he replaced the VSS with a new one and says he has no idea how why it doesnt work while everything else is running fine for the tacho and gauges. Also I know the car doesn't have ob2 so if I want a diagnostic system could I find an adapter like this
http://www.amazon.com/OBD2-Connector-Di ... B0053NS0CY and use a bluetooth ob2 scanner since I have one laying around and use an app on my phone that can read ob1/consult code? I mean its 10 dollars and there are a couple free apps that can read consult so I think it would work pretty well. Dont think there is too much info on it out there on quick diagnostic systems that arent a nissan datascan
I want to make sure if there is any fixes I can do instead of spending 100+ on a new VSS or a decent cluster. If its the cluster then i'd want to swap with a 180sx koukie cluster from a local shop in south fl called Drag International which looks reputable. Hopefully they can do the install and do a speedo adjustment from KMH to MPH. Here is a picture of the car which I forgot to say is 1993 240sx s13. He also sold the pig nose sadly /: I might do a build up thread since I plan on doing major things with the car for the next couple years with a goal of 300whp on a KA, make my own custom cluster, then do some 180sx bodywork, and add a bagged suspension. I want this car to a functional DD and try to push out some decent MPG since ill be starting college in a few months. The owner at the moment has a pretty good history of the car and has babied the car a lot and done all the work from rebuilding the engine, bodywork, tune, and turbo install from his friends and family. The car is a steal of a price for the amount of work and time put into the car. He has quite a long list of mods and the car is running 223whp at 6psi with an enthalpy tune and safc ll which everyone will tell my to throwout and burn to the ground lol
But yeah any info on checking cluster wiring or the VSS would be helpful to diagnostic if its the cluster itself thats fried or the VSS is also finished after that ill go from there. And any info on a easy diagnostic setup would help also since only the last week I realized the car doesnt have ob2 and have been looking around like a mad man to have pretty cheap and clean system to check general engine problems and such. Thanks!
