Though I'm sure you are/did already...'Just be sure you received the B184"
M" = MERC as reading the descriptions says the needed parts comes with the M controller to make Merc type/style cables work...Are there any other parts inside the box, etc.?

- This still looks a bit like to make any Mercruiser type cable work, this kit needs to be installed....So ordering new cables might not be the correct answer....Yet.....
As mentioned in AD's PDF link above on pages 155 Your 600A cable is also known as a CC179** (*13ft) cable number from Teleflex which is also comparable to ULTRAFLEX # C5-MACH5 (< That is should you end up having to go with a new/another type cable to work with this controller)......
