1991 300D 962.961 vacuum circuit problems

Hey,

I am swapping a 1991 2.5L diesel into a 1997 Jeep Wrangler and nearing the end...in more ways than one. I believe that I have stepped down the motor from electrical to mechanical based on helpful posts from this site.

So, I want to have the engine stop when I turn off the key. I have read about om617 engines using the eng. overload valve. I would like to do the same. Below I have a photo with what I hope is the 962's overload valve.

1. Do I plug the outlets from the alda to the "Charge Air distributor"?

2. If I connect one end of the tubing to the overload from the "Stop Unit" where should I connect the opposite?

3. With power on the circuit should be closed to run/open to stop?

4. Should I close off or loop all the auto trans vacuum lines since I am running a manual.

I am going off of the pdf for a vacuum line routing on a 602.96 w/ manual from my MB manual.
Thanks

Thanks pwogaman. I have the PDF for the circuit. I am just trying to make certain about the shut-off, auto trans, etc. I want to reduce the vacuum leaks and cranking before I restart this motor.
