I do not have a serial number for new engine as it still hasn't come in (ordered last week of May 2018). I have replaced the old 8 pin harness with a new 14 pin cannon plug style harness with all new controls and smartcraft SC1000 Tach. Have the 4 port smartcraft junction box and the acc. harness from merc. My question is what other items will I need to hook this new engine into my Humminbird Solix 12?
Thanks.
