Taligate switch.  My factory Chrysler parts book says it fits 81-90 L body.  However, a good buddy of mine said it only fits 1978-1983 Omni with 4 doors.    So before you purchase, please do your own homework.    In any case, it's brand new OE Mopar.   Comes with the cool 70's-early 80's Mopar box as shown!
