Does anybody know if a fuse box and wiring harness from a 1995 k1500 will work in a 1994 k1500, or one from a 1994 c1500 work in my 4x4?

 

Most parts from the "C" series and the "K" series p/u's are interchangeable, but with a fuse block thats where you need to do your homework. 4x4 models may have fuses inside the block for the 4wd actuator and other components not found on the 2wd models, also depending on the package, if it was a base model, WT (work truck), or Silverado it may have additional fuses within the block to accomadate fog lights, a different style dome light, or other accessories. if you can match up the fuse blocks and they look pretty close you can probably use them, and if your missing some fuses on the block you can always wire them up yourself, not to difficult just check your local parts store and see what they have. best of luck...
