10 4. That's the way I'm leaning because I don't know for sure it's programed for demandate. I found the block off plate at the end of my work on it. It was 1 am and I was ready to get to bed so didn't dig deeper. He just asked if I could look at it because if it was to much he was just going to sell the truck. I found some burnt wires caused by an exhaust leak so figured that was majority of the problem but nahhhh. I'll have to call customer and see all that was done to that truck . Thanks for the responses
