Greetings Catmen, Question , the wires that run into the back the of the superdash are they connected to the unit with a plug that can be pulled out and cleaned? my tach and speedo only sometimes blank out or give crazy readings. I could care less about the speedo but the tach Im concerned about.Last edited by ol skool cat on July 22nd, 2009, 7:44 pm, edited 1 time in total.
