ok the connector for the cd player in my truck is different for the casset player (stock) in my blazer..and i noticed in my truck..the connector wires are all spliced into other ones. is this becuase the cd player required a different connector? and do all cd players come with there own conncter..that you splice into your existing hook ups? cuase i thought they were all universal. and would another cd player hook up in my truck? are cd player and casset connectors different? thanx!
