M46 swap that's 98% done

[Sam Vetter]

This isn't a guide thread as I'm looking for guidance myself. I'm trying to hook up the o/d into the new m46 and I cant figure how it knows it's in 4th. I've got the harness on the transmission and the one on the stick itself. What goes where is basically what I'm asking so I don't destroy the tranny as soon as I go into reverse and it tries to kick on o/d. Any and all help appreciated!
