I will order a ZIP ES-510 and report back: 1968-1971 ,,,,,,Includes original type "pin" connector with terminal, correct color wire and asphalt insulation.
Hum thinking out loud here >> Terminals & Nomenclature.
Spade Style = Flat Male Metal Packard Series 56 or 59.
Pin Style = "T" shaped cross section button head mushroom
Stud Style = Threaded or unthreaded Round stock
I messed up my Orig harness and put a larger diameter covering on mine, I found a vendor whom sold the brass pin-terminal & white round plastic housing connector & now I can't seem to locate that seller again a year later.
I will post results.
I think I had checked with the "Packard series" terminals supplier Texas Industrial Electric Co. and they did not have the pin style available either. I also performed a salient characteristic search of terminals via Digi-Key and came up empty. I want the correct terminal, Funny I see cars all the time with a female packard series or Thomas and Betts female terminal with the spade style forced onto the stud,,,,,
