Check your oil pressure sending unit and wire,it may have gotten damaged when you bottomed out in the mud.looking at the motor it will be to the left of the oil filter.

 

You may be right, but I couldn't help yet.
I don't know what year or model bike he has. Filters and sending units are in different places.

 

Yes more info would be a plus.

 

Punctuation as well.

 

2004 1200 custom I'm looking at it and a few wires and harness seem a bit loose but nothing seems off or broken

Tell us what the problem is, hard to pick it out from the original post...

 

Swapping parts will cost you a lot more in the long run.
First Check for codes if you are getting the light there will be one. It requires no special equipment to do so.
It could be a damaged Crank sensor also the code will likely give you a pretty good idea what is causing it.
Also year and model would help a lot.
