Where do I hook the transmission lock down cable that goes into the idgnition sy

What is your question?

We recently had the motor changed out on the car. We also had to replace ignition tumbler with new keys. When doing so the dash was taken apart and we found where all goes except where to plug in the transmission lock down cable that goes into the ignition system ?(that's what I'm calling it so I'm not sure if that's the right word.)
