88 k2500 stereo wiring diagram needed

[carter442]

just as it says i am needing an 88 k2500 wiring diagram i just bought a stereo for my truck and will be wiring it into my stock harness but i do not have the diagram. so if somone has one i would greatly appreciate it. i believe my truck came with a factory cassette player cause i had one and it had its own harness im not sure if that will change it but im adding that.
