999 lock up wiring problem

From what I understand

It’s a preventative device to shut the converter lock up off. When I’m towing mode

I got very busy in life and didn’t have time to mess with the car. Now I’m going back through it and replacing stuff to get it back on the road.

So I’ll be revisiting this as well.

I did get some more information on it
I understand the idea to turn off for tow mode but I have an A999 supposedly from a Dodge Magnum. Would not have tow mode.
