This harness was easily installed. Anyone with basic electrical knowledge can use this part to replace their worn out harness.

I have a 40 hp 1979 serial number 5482532 I need the battery leads and the wires that go from the ignition on back to the battery that is shown in the bottom picture that is included as well,right?
Yes it is included. If desired we can send you the instructions for this part. You will just need to call us at the number at the top of the page.

I have a 90hp mercury inline 6 SN# 4846354 i need the internal harness? the plug on this one does not look to match mine can you help?
This is a replacement for your motor, so if yours looks different then something must have been adapted. You can contact CDI Electronics for more guidance or contact a local Mercury dealer.

How many prongs are in the engine plug and how long is the complete harness, I have a center drive deck boat. Thank you?
This is an internal engine harness so CDI says it is standard length to the outboard motor you have. If you're looking for boat side harness then you need this (battery leads 6 ft, overall 20 ft, and 7 prongs):

Will this work on a motor with the serial # 5174828?
We would need to know HP for sure and year, if possible. If not we can usually find the year. Give us a call if you would like assistance with that at 1-800-914-1123.

CDI part number 414-2770, what serial range does it fit for my 90 HP, inline 6 Mercury?
Serial range for that is 4845301-5299505. So if it fits between those numbers it will work for your engine.

I have a 115hp mercury inline 6 with 4394720 serial number. Would this be the right internal harness?
Yes this is the correct engine harness for your motor.
