How do I install Gate Aster 2 Bluetooth in Krytac CRB-M?

Ad the title says, I would like to know how to install the Aster 2 Bluetooth rear wiring into my Krytac CRB-M please. I had an issue where the wire broke from the fuse. As my version is the partial mosfet I believe some one said. So I have the fuse connected to the deans battery connector. The wire pulled off right on the fuse. The rear part where there's usually the mosfet is empty. Instead there's a circuit board under the trigger. I was told to replace it all with the Aster 2 Bluetooth model. So, im wondering if there's a specific way to install it or if there's a video out there I can't find on how to install it for this gun. As well as, if i need the fuse still or the gun doesn't need a fuse anymore? Or do I need to attach somehow?
