Reply To: How to wire cutoff switch for 1970 Evinrude Triumph?

OK, this engine has battery CD ignition, no black/yellow stop wire used here.

The best way would be to put a safety switch in between the battery B+ post and the lead connected to it…  That being said, I don’t recommend doing this, unless you use a rugged/reliable switch and do the wiring in a way where it won’t break/get chafed, etc.  There is not much room inside that box…
