What year is your 300FW? Got the VIN handy?
Did some research - for 1988 the original CDI box was part number 30410-HC4-003 - for 1989 thru 1993 part number 30410-HC5-971 which superceded to 30410-HC4-770 was used. Then in 1998, the part changed to 30410-HM5-A11 which superseded to 30410-HM5-S01 which then superceded to 30400-HM5-506 - this unit was used on all 300's (2 and 4 wheel drive) from 1988 to 2000.
In all cases, the CDI unit is DC with 12v fed in on the blue wire with the white stripe.
