question on wiring harness

[BillProctor]

I have put a 2003 yamaha 115hp 4cycle engine on my 21' pontoon boat. the engine is off of another boat. the wiring harness is short by about 4 ft. when i started looking for an extension I had trouble finding one with the same number of pins. turns out that the harness was modified by the boat manufacture and the connections are not yamaha. I'm having trouble getting the correct harness. I unplugged the harness at the engine and it shows to have 9 pins. all i seem to find is 7 pin harness or 10 pin harness. Can anyone direct me to the correct harness, please. model F115TLRB

An F115 uses a ten pin harness even though the motor side harness only has nine pins.
