DvR posted a topic in Boat TalkHello boaters! We have a 2007 Chaparral 350 SIG hard top. The helm navigation switch we think is broken. We need a electrical harness schmatic to undertand what plugs into what! Does anyone know the name or contact info for manufacture of the helm electrical switches? We know the lights work, we just need an understanding where to reattach. thanks fellow boaters.
