Dash Cluster Printed Circuit Board differences
FYI - I had a heck of a time this summer rebuilding the cluster on my 76 Feather Duster. Had a mint cluster from my 74 Duster so I decided to swap it into the 76. The main connector fit fine, but once powered on nothing worked correctly and a few of the 74 gauges got fried. Turns out the PCB's are different. In the first pic, the PCB in the middle is from the 74. Notice that the ammeter (2 holes all the way at the right) is NOT powered from the PCB, it's got its own wires which connect to it. In the next pic you can see that the 76 PCB powers the ammeter. So there are 2 extra pins in the main plug to feed the ammeter.
Just so you know that not all the PCB's are the same. Not sure about 1975 ones.
