this truck was brought to me original vin 1GCEC14X19Z197974, customer brought it with 6.0 swapped into it with 6l90e transmission, the os on the swapped ecm is 12622142, anyone have a segment file for this? couple gauges dont work and i just want to make sure its not programming. fuel gauge doesnt work, and oil pressure doesnt work, checked with mechanical gauge and it has pressure and also has new sensor.
