I just installed a 4L60 into my 1966 Impala to replace the original Power Glide. I moved the cross member, shortened the driveshaft, converted the VSS to analog speedo, and, adjusted the kick down. All I have left is to connect the back up lights so when I shift into reverse the back up lights come on. Can anyone help with where the connections on the tranny might be to accomplish this might be or do I need to so something else. Thanks.
