One possible solution I can think of, is to remove the connectors from both optos along with what ever wire is still attached (Blk/Yel, Gry/Yel wires only!) from the rest of the playfield harness, post it to me and I should be able to add a connector for 2J16.  Just to make sure it will be long enough I can add extra length.

Edit
To save on postage, take a photo of what's left of the existing harness once removed.  Probably won't need it all.
