I just recently purchased a Peterbilt with a c-13 and a 10 speed eaton. It has a bunch of random issues with the headlights staying on then the running lights will stay on. Does anyone have the electrical diagram for this truck? I have been on Supermiller and the diagrams are close, but mine appear to be different?
