I hope this is the right spot for this. I am getting ready to pull the under dash harness from what I think is a 90 or 91 k1500 5.7 5 speed. before i do I would like to know if it will be compatible with with a 94 454 4l80e truck was born 6.5. I know the gas diesel harness/fuse boxes/junction boxes are not the same. I this is a big part of why the fuel pump relay coil and dizy have no power and no injector pule with noid light but it will crank. just to be more clear when I say junction box I mean where the engine harness and cab harness plug into the fire-wall.
