Needing Basic Whelen information

[AP330]

Hello,
I’ve kind of been thrust into my new position. I’m semi experienced with emergency vehicle lighting but not with the wiring and ins and outs of these controllers. I’m looking for help on adding in lights to our current system which uses a 295SDA1 for command vehicles. I’m adding these lights to be included into the main 3 position (4 technically) switch. It appears from the manual that J2 is powered for that. Where do I begin? The manual isn’t explicitly clear. I normally would go back thru one of the lights to figure out how it’s wired in but since this is in service I’d rather not do that.

Thank you.

Looks like the easiest way to add on three is to tap off the white wire on J2?
