hi guys im building a rat rod and im using a 94 turbo diesel . im wanting to simplify the wiring harness starting with the motor first . its pretty cut and dry on how to start it and the glow plugs , but my question is how do I kill it after I get it started . question 2 . their is a couple plugs going to my pump and im guessing one of them is a fuel shut off , any help would be nice
