TOPIC: Help needed: MFG key ignition question

Hello all, I have a 1974 MFG 15 foot boat with original Evinrude 9.9 HP outboard.

Lost the key and I want to replace current key ignition which is a 5 prong wire (see picture attached).

Im not sure how to match up the wiring on this older igntion switch to a newer part. Has anyone ever done this?

thank you
