I'm surprised no one has grabbed the reigns and started making a shooter housing with lights like these for use with Jurassic Park and Stranger Things 3rd party shooter rods.

I'm not sure if or how the 2 controlled lights are implemented in the code on each game or even if the Jurassic Park and Stranger Things Stern shooter housings are wired the same on them both. They could very easily use the "Spare LED 3 and 4" connections on one and the "Spare LED 5 and 6" connections on the other.

I rescind my thumbs up for your schematic post....as i think it is incorrect.

Here is a pic that someone posted of the wiring they got with their Stern Jurassic Park shooter rod. This is what plugs into the CN15 connection. It appears the 3rd and 4th pins are used and not the 5th and 6th pins as you have designated.
