01-02 trucks use a standard sending unit that feeds directly to the gauge cluster, 03+ trucks use an oil pressure sensor that goes to the ECM and the ECM transmits the value over the J1850 data bus. You MUST use the trucks stock base file for 03-05 trucks unless you want ALOT of WIERD quirky issues.
