If I understand correctly, somewhere along the line these 2 wires connect into the one going to the key switch? If I run a new wire from the key switch to the engine, I would need to split it to join the 2 black and yellow wires?
Just bought boat with 1999 Mercury 175. There doesn't appear to be a physical kill switch, but there are the usual black/yellow wires going to the switch box. I'm having ignition issues and it seems like the kill switch wires have been tripped. If I disconnect the black/yellow wire from 1 switch...
