71 Duster Door jam switch

Thanks for the info Dubob. The 3 pin connector has one stud that is badly corroded so I'll need the plug too....if I can't find one to wire in, I'm contemplating seeing if I can carefully remove the metal pins from the plastic and push new ones in....OR using the two prong connector and putting two wires together on one prong. When the switch opens it provides continuity to ground for all three wires so open it should work fine...I don't know how connecting two of the wires will work when the switch is closed with no continuity...seems to me like it should, but I'm electrically challenged.
