Here is a diagram of the Emax F1 + OSD FC video hookup. Please note that while the F3 is different the hookup is the same, just check you have the right tabs on the underside of the board.
All the topside connections remain the same.
*Please note, in most cases the ground connections can be omitted, so only Video in and Out are used. If you have any problems you may need to connect them.
