Plymouth Duster Instrument Cluster Wiring
Look at the ammeter, no 20 wire, this is a 72 Fury. A11-20R and R16-20BK these go to pins 9 and 13 of the bulkhead connector. From there you can follow them in the engine bay R16-20BK connects to junction "2" which is in the alternator output The remaining wire connects to junction "3"
This is exactly what they did. I believe GM, Ford and Mopar all used the harness You can see this if you look up about a 72-ish boat, like a Fury I think
