It seems Tyler's review just beat mine by a few days haha.
On my 1983 PA50ii, the green wire and the black/white wire go onto either of the middle pins #1 or #2.
The solid black and red wire go to either set of pins #3 and 4 OR #5 and 6. Ignore the other set unless you want to actually create an accessory position for say, a stereo or phone charger haha

Seems more robust than the original ignition. Haven't installed it yet, but it does not come with a diagram so I figured I post here to save some folks some trouble.
Position 1 (off): Pins 1&2 connected Position 2 (on): Pins 5&6 connected Position 3 (acc?): Pins 5&6 connected + Pins 3&4 connected.
So for a PA50, ignition wire and ground would be connected to 1 and 2 to kill the engine in off position and voltage would go to lights through pins 5&6.

got this part for my pa50ii, sorta fits but needs a washer to make it sit snug with the original opening and the wiring harness has 4 wires to the ignition switch not 6 so still haven't figured out how to wire it properly
Not really for PA50s, but does the job
