" I just replaced my 1962 75HP
" I just replaced my 1962 75HP V4AL14 Johnson engine. I cut the electrical cables under the dash, leaving a long enough tail. I replaced above mnotor with a 1971 50HP 50ES71 motor. Motor is running fine. Questions: the original 75 HP had a tach and I want to know what wires I need to connect from the 50hp to the wires going to the tach cut under the dash. Current 50 hp has 13 wires from motor to control box. If I take positive and negative wires from control box and tie to wires under the dash, will this activate my existing volt meter, fishfinder ,lights etc. "
