Same components used as my other cdi board just incorporates an 8 pin mini din. Made to be soldered into the rf space of a cdi 220 console. First, desolder the rf box. Then solder on components and din to the pcb, then flush cut and tape bottom. Then solder capacitor or resistor legs from bottom of the motherboard through the rf slots through top of motherboard. Then place pcb over top of the legs, align board, solder in, and flushcut the legs. Can use an md 80sm din from digikey or mouser or uxcell from Amazon. Install wiring guide at retro rgb .com
