Depends likely on when those 16 years were. The newer and the larger platform cars went to external shunt ammeters. I've seen several "back in the day" (early 70's) and one was my own 70 RR WAY before Al Gore invented the internet, I drilled out the two big ammeter wires terminals in the bulkhead and ran larger wires "straight through" the connector. I had to take the cluster apart (plastic cluster housing on a 70 Ralley dash) and repair the loose ammeter terminals.
