1971 Slant-six ballast resistor ID
I tested my resistor today and I found 1.2/1.3 Ω
So, it's not the good one.
I will replace it by a 2095501 original Chrysler resistor (0.5/0.6 Ω)
About the connectors, I found this picture on internet :
And the owner claims that its Dart has only 10k miles. So, I suppose that the connectors are original.
