zongshen cb250 wiring/cdi question!

hello forum, thanks for letting me in!

i have a euro4 (efi) hanway 125 that i am playing around with.

i have bought a zongshen ''cb250'' engine (single cylinder) and it came with no info (nothing new i am told!).

i know i need to buy a coil and cdi box for this engine but cannot find out what the 5 separate wires are for (the block connector is for gear indication) and then work out it is AC or DC cdi type.

hope this picture link works!
