ight i have posted something like this before where i wanted to swap clusters, see my 1990 civic dint come with a cluster with a tach, and i heard its just a plug in play if you get one from a 90-91, well i bought one of each a 90 and a 91, and they dint work, so im now thinking i have to rewire them? which im really not tryin to do, so whats the deal pickles, what do you guys think is wrong here?
