find this diagram in
your model's owner's manual. This is from my 2000 365 express. The switches were the McGill Euro Oval switches. THEY WERE CRAP! I know this is hard to see but it explains alot once you understand what you are looking at.
It even shows the (original) wire colors. It help to understand that there are different types of switches like SPST(singlepole-single throw) and DPDT (double pole-double throw) and SPDT.
Newer boats had Contura style switches and more terminals on the switches.
Lighted switches have more connections than unlighted switches
Notice that the Nav/Anchor switch has two special jumpers
