ahhhhh im gonna punch my tach through the cluster! 90 shelby. Fixed tach 3 times in the last couple yrs. last 2 times it only lasted for maybe a month each time. I re melted all the solder spots on the back of the whole cluster each time and even added new solder. between fixing that and my stupid turn signal with the super dumb hockey stick lever every so often Im gonna hard wire my whole car lol.
