I am going to assume that this may be a internal sol. Ford C-4. I use a cast aluminum pan with a Chrysler 904 pass through connector. Transtar transmission parts sells them, the single wire is part # 12444A, the two wire part # is 12444B. this connector has a 1/4" NPT thread and is leak free. One more option on a internal sol. Ford C-4 assuming you do not need a speedo, is use a Turbo 400 pass through connector Transtar part # 34444B. It fits well into the speedo hole in the extension housing and just run your wire through the back of the case near the park mechanism access hole. Also leak free. Louis Jeffery
