That was every year for MOPAR! :rofl:
Something changed almost every year. I bought 74, 75 and 76 service manuals to figure out my wiring. LOL Even things I know of that changed like bumpers and guards can be a head scratcher when people tell you they know something is original on their car, yet it is not the right one by the month and year of production. "Hey Sam, found this in the stockroom", "Put it on the next one":lol:
