70 Swinger Dash lights

Thank you again fellas',, you are building my courage,,, I read some where the wire harness is very short and stiff,,,if there is a plug/connector for the dash instruments,do i undo that from below,,,same goes for speedo connector. Or pull dash out carefully,,, to gain just enough access to those 2 things.......I thought maybe I did not have to drop steering column,, on a car with the rally dash,,,,,
