2005 Sportster 215 wont crank

[Mastapoole]

So I have a 2005 sportster that sat for years. I finally got it to my new home and so far ive put new fuel new battery and a new neutral switch. When I put the key on the post i get two beeps followed by a short pause then 4 quick beeps which I read online was the boat not knowing it was in neutral which is why I replaced the switch. Any ideas on next steps? would love to get by this electrical issue to see if the boat will fire up. Thanks for any and all help.

I would trace the wiring for the neutral switch because if you replaced it and you still get the 4 beep, I would say the ECU doesn't think it is neutral.
