Have a 72 65 Hsp Evinrude that has 12 slots on it. Don't have a book that goes back that far( only to 73 and it's different). Here's the colors for the slots. 1-orange 2-orange 3-orange 4-brown 5-brown/orange 6-black/yellow 7-vacant 8-white/black sensor1 9-white/black sensor2 10-white black sensor3 11-black/white 12-black. Like to know where each one goes, and also what the sensors are all about. Thanks for your help. Skip
