If you go to Sears.com and then parts direct. Type in your model number and they will show you a wiring diagram which should help you find all the safety switches.
Sorry, I'm a wrench monkey not a computer nerd.
is this the one..?
This could be it. I'm trying to locate the actual location on the tractor. I've been told it is on the right side of chassis below the engine. Thanks for you feedback. It is very much appreciated!
I read this thread but I didn't see where you answered if the engine turns over or not. Just curious, did you disconnect the battery anywhere during the engine swap process? If so, make sure you put the leads back on the proper battery post. Sounds silly but I've seen it done before. If the leads are backwards the engine will turn over but it won't start.
Thank you for your interest and reply. I have a successful update to my saga with this engine swap. After much effort, I discovered that I had blown the 20 amp fuse while re-connecting a wire on the mismatched wire harness incorrectly. After replacement to the fuse, and the proper hookup of the kill wire to the ignition switch, I now have a starting, running, and stopping tractor thank you all for your very helpful responses. The engine swap is a success!
