Greetings, Just replaced an 3.8 engine in my 1998 Grand Prix with a 2005 3.8. The only issue I ran into was the alternator mounting is different, so I purchashed a 2005 alternator. The plugs are different between the two. They are both 2 wire, but I can't follow the schematics. They appear to be different. Can I cut the plug off the 1998 harness and splice a 2005 plug in it's place? Thanks
