okay kinda looked around here but, i didn't really see any threads to cover my issue. first my tach lights wont dim at night, makes it hard to see with it so bright. second my speedo is sometimes 20-30mph fast or slow. doesn't seem to have any rhyme or reason to it. when its showing me running 20 mph fast, then when i come to a stop the speedo needle is well below the zero. turn key off and back on it does full sweep and is back being on zero and working properly.. ? the tach #'s appear to be correct as far as i can tell.
