I was asked to post this here.

1969 B-body
It goes in the small 2 wire weird shaped plug then into the top 2 left connectors on the firewall junction block
Connects to the switch on the trans, runs along the top of the trans,
And I think at the firewall it has a white plastic clip in the harness where it slides over one of the tabs on the firewall
( Need to ck again)
