Ok, I have an 88 supra turbo and I am trying to replace the stock 102k mileage gauge cluster with a gauge cluster off of an 89 N/A car with 200k miles... and I know that these clusters are considerably different... and I'm pretty sure that the new one is going to just plug right in... nothing does with this car. I'm sure that someone has done this before and would really appreciate it if anyone could give me some tips or tricks or walkthroughs or ANY kind of advice for this little project... Am I going to have to cut the harness? Which wires are which? And where do I hook up the voltometer? Also, what's the best way to turn back the mileage on this car? Any answers to these questions would help me out alot and I would really appreciate any feed back. Thanks!
