I am switching my engine out of my 99 accord to a f20b but I am being told that the engine wiring harness would have to be switched out. I have searched and I have not found any information on that at all. Will I need a different harness or will the one I have work just fine. I was also told that I would have to change my motor mounts. Anyone with correct information on this would be great. Please if you are unsure then don't bother to comment for it'll just be like me searching thanks alot!

 

Might have to re-pin a few wires or it wont start is what i heard
here is someone who did it
