Electric connection
 

A freind of mine has a 2002 AO NSX that has a 496, He bought a 525 for it and the 9pin male connector on the wiring harness from the boat will not work with the 14 pin female connector on the new motor. The question is: has this work been done by someone else already do we have to splice all the wires for the boat or is there an adapter someone knows about, any help would be good. Thanks
