Well, crimp on pins will work... But just not the optimal nor nice looking solution for these feed thru type connections.
I don't really see a good solution unless you want to give the two wires into one contact a try. Not the easiest to do and defies all 'proper crimp' rules but does work.
Clay had a photo of this on his website but I cannot remember his website... maybe somebody will chime in on this one. I know the guy that submitted the photo of this and he kind of regrets submitting the photo since it isn't exactly what is considered a good crimp particularly on the insulation crimp.
