Installed new ignition switch, now motor won't turn off

[JasRam]

I have an Evinrude SPL 28 and I just installed a new ignition with a kill switch. I swithched from the type with screw connectors to the kind with round male plugs.
The one I bought is an OEM part. I started the boat today and it started perfectly but it wouldn't shut off. The only different thing I did was plug in the red/yellow wire to the S terminal. The boat was perfectly fine with the old switch but I'm not sure how it was ever working, as I couldn't see any evidence of the yellow/red wire ever being touched. I spliced into it, as I found afew diagrams online that said to do this. I figured I would test the kill switch so I just started it in hopes of just letting it pop out and stop, this didn't happen and it kept running until I pulled the plug wires. Could it be that I have the M terminals switched?

I read that the yellow/black and black were interchangeable. I also could not find a red/purple wire but directions I found online said that I should.

Here is the one I ordered

What did you do with the old safty lanyard switch and wiring?

I have a 1981 Evinrude 35. I have the same problem. The wires and the power pack were fried when I got it. I told it needs a ground wire however no one said from where to where. So good luck. I will have to see what you come up with.
Good luck !!!

I still have it, it was just the simple turn key with the push in for choke. It didn't have a safety switch so I wanted to install this new one.

What year is your 28? Model number please.

What year is your 28? Model number please.

Hello and thanks for the response. I figured it out, I had used a quick connector to connect the yellow/black wire. It wasn't crushing into the wire enough to make a connection.
