Toro Proline safety wiring (pistol grip)

I have a toro Proline 48” walk behind mower. It’s the pistol grip operating system. The safety kill system doesn’t work and I have a red and a black wire that attach to nothing. I’ve researched diagrams all over the internet and I can’t figure out what needs to be done to reconnect the wires and make the safety system work correctly. Both wires come from the module under the gas tank. Anyone got any experience with this issue? Thanks!

What is the numerical model and serial numbers?

This service manual has a wiring diagram which should help you out. https://www.toro.com/getpub/30747

My diagram is on p. 156. Unfortunately, I have that and have been looking at it all along the way. The “B” wire on the diagram is running to a rectangle labeled “mag”. What is that exactly? The “E” wire seems to go to ground. Is there a grounding location on the mower frame? I don’t see one…

Then it shows the “mag” feeding to the ignition module. Where does that connection occur? In plain sight or somewhere under a motor shroud on top?

I’m guessing you have a key switch which is used to kill the engine. On that switch there should be a black and red wire attached. If they are not there, that’s where those two wires you have hanging go. If they are attached, then you need to find the module, as that is where they come from. If you would have looking through the manual I posted, you would have found this, “THE INTERLOCK MODULE IS CONNECTED TO THE WIRING HARNESS IN THE UPPER HANDLE/PANEL AREA.”

I actually don’t have a key switch. The throttle stops it. Push it all the way to the bottom and it kills it. Push it all the way up to choke, all the way down to stop the engine.

Then someone has rewired this unit. We’ll need some pictures of the wires, where they are hanging, the throttle control assembly, and the areas where wires are coming from. Remember we cannot see what you have and must help you locate your shutoff switch.

IT seem someone disconnected part of the system to bypass the safeties. I could help but I have seen one these mower so I have only the service manual to go by. As you I am what that MAG object is. I would assume the connection are under the shroud but is just a guess. Sorry that I can't be of help.

I’m trying to post pics, but it says the files are too large:(. I may take the engine shroud off today and peek under. I appreciate all your help. I could send pics via text if anyone wants to assist to that degree.

How about a carb couple of pictures of the entire unit and where the throttle control on the engine. I need to see how it has been rewired.

Carb is brand new, but I’ll post more pics.

Ok, I’m getting a little better picture of what is going on here, definitely a rewire to by pass safety switches. Here’s what I would do, how you wish to proceed will be up to you. I’ve attached a parts catalog which should help you locate parts on the unit. https://www.toro.com/getpub/25658. Hope you’ve had some electrical experience. Here’s the steps I would follow.
1. Printout the wiring diagram on page 156 of the manual provided earlier.
2. Printout pages 4-5 and 8 of the parts catalog I just posted. On these pages located the three safety switches and module which will need to be wired into the circuit. If you look closely at the pictures, you’ll see the approximate location of each switch.
3. Remove the electrical tape from the DIY guys attempt to be a mechanic. Don’t disconnect any plugs.
4. Using the wiring diagram trace all wires following the color code, to identify each component.
5. At this time you should be able to identify where your two unknown wires go.
6. Using temporary wire nuts and test the unit. If it doesn’t work, test the safety switches, for continuity, to see if they are working properly, with a multimeter. This can be done earlier if you want.
7. Hopefully everything works properly, so remove each of the wire nuts, soldering the connection and coat with liquid electrical tape and electrical tape, to protect it.

Warning::: Electrical troubleshooting takes the patience of Job plus a special education teacher, so don’t be afraid to have an assistant around. I’ve done this type of job many times and some take 30 minutes and others have take 2 days. Double check everything you do and then check it one more time. As you go through the procedure don’t think you can remember each step you did, you’ll forget. Take before and after pictures of what you did after each step, they’re easy to delete two weeks after you complete this project. If you have doubts or questions ASK. It’s easier to ask a dumb question, than fix a stupid mistake. There are tech here that know their crap and will be willing to help. Also, each of us do things a little different so don’t think that one might be saying the other is wrong. Good luck.

Thank you for this. I really appreciate it. I’ll report back:)

Would it be necessary to take the engine shroud off?

My red and black are the top 2, to the right of the #42 in the pic. One appears to have a circle end for the ground and one has some sort of plug. Those are the mystery wires. Where do those go??

The part you are asking about is the interlock module. I’m thinking the wires that are disconnected go to the safety switch, part number 13 on the same picture.

Unwrap the wires to see what the bypasser did. It looks like they removed the wires going to the engine too. The wire with bullet terminal would to the engine under the shroud to the ignition coil kill terminal. The one with the ring terminal would be a ground connection,

I also rotated the image to give a better pov.
