I recently purchased a wire harness and control box for a 1998 Johnson FICHT 150. It turns out the control box is prewired but the wire harness is not for a prewired box. I have figured out the nutral safety switch and need help with the Kill switch. It is wired in to the ignition in box but the wire harness has a couple of leads that says safety lanyard switch. How can I hook this up so it works? Thanks in advance for any help.
