FW21 PRO Driver Help please!

Hi everyone,

I was trying to add thicker wire to my FW21 Pro driver and it seems I managed to dislodge 3 of the microscopic components from the board (C4,R4,R3). I’m guessing I need these for the light to work. Does anyone have a wild guess what those parts might be. Could I maybe just rob them from an FW3A and get the light working???

This board is from one of the prototypes that was so its already been worked over a lot before I ever tried replacing the wires. I’m not 100% sure there were components in all 3 of those slots, but I know for sure there was at least one because I found it stuck to something.
