Here's what I can make out from the diagrams I have with reference to the wire colors you posted.
yellow / black, - Terminal "C"
yellow/red, - Terminal "S"
blue - Terminal "M1" ( note there are two M terminals, so I used designation M1 and M2)
black/yellow, - Terminal "M2"
grey/black, - this could be another accessory like tach, fish finder, etc. you need to find out where the other end connects. If it is an accessory then it connects to the Terminal "I"
green,- From the pics you provided this looks like green/white instead of a solid green. Verify if this is solid green or green/white
brown - this could be an accessory like tach, overheat temp buzzer, etc (if it is an accessory, it goes to Terminal I"

There is one important wire missing and that is the red wire or red/purple wire which comes straight from the ckt bkr from the solenoid and it goes to the Terminal "B"

Here's a wiring diagram. It's a little small so you need to save it to your computer enlarge it and then print it to make it readable. YOo must verify all wirings are correct before you power on otherwise you could fry the CDM and it is a very expensive component.
