i put this in electrical but its not getting anywhere thought i would try over here too.

i am swapping in a tach cluster from a 78 k10 to my 74 c10. i am trying to determine the wiring order on the main plug. looking at the 2 attached diagrams i can see where the wires need to move but there are several that are plugged in on the 74 harness that im not sure what number they change to. can anyone enlighten me on how the wiring should be.

the diagrams are in this post. http://67-72chevytrucks.com/vboard/s...d.php?t=357071
