853/863 Compatibility question

[mike11]

Hopefully you guys can clear something up for me. Recently I got an 853H that someone removed ALL electronics from, it’s now fully simplified with only a few gauges, I want to get the aux hyd back up and running. I did find a full aux harness and pwm controller from an 863 available. Would this work plug and play ?

Thanks

I would check part numbers, if there the same for both models, then, it should be! if not?
