Weeeeeeell, I just did this a couple weeks ago. Let me tell you something...PATIENCE!!!!! oh man, I was ready to kick the crap out of my car while doing this mod. I have a 92, and I went to the 95 gauges. If you want to do this, I will tell you exactly which wire you need to wire to which pin, and will save you HOURS!!!! of time. I know exactly what to do, so email me if you want the info. Oh and btw, I LOVE the gauges....they are so kickass
