T5 transmission back-up light switch

[akqj9]

I have the T5 transmission with a back-up light switch on the side but I need a female plug to hook up my wires. Non of the parts stores have one. I probably could just wrap each wire to a pole but that is cheesy and would not hold up. Here is the switch, what part number would I use? I don't know the year of the trans but the trans shop I bought it from said the switch fit many years of GM.
