    Anyone know where I can find the schematic and the plug identification on the wiring harness from a 1990 3500 454 ? I removed a 454/4l80 out of a 3500 and computer with the engine harness and now I have a couple plugs that I am not sure where the go or they could have not been used . My problem is no power to fuel pump checking at the fuse (fuse good but no power on either side ) can put power to fuse with jumper and pump works but the injectors are not firing . I cranked engine before I pulled thanks in advance for any inside info put it in a 91 sport truck

    Somebody posted a whole bunch of wiring diagrams on here not too long ago.
    Hopefully they can see this and put the link again. Ill see if I can find it.
