Single wire reverse light switch for 68 Barracuda

My car is auto on the column and I looked up the switch part # 2857 240 I see that switch is actually on the steering column. I guess I'm looking for the neutral safety switch only for single wire? The one that was in the trans looked similar to the newer 3 pin style but only has 2 pins? I thought it might have been broken. Just trying to put it back together right and have everything work as it should.
