The default files used by FSX for contrails are as follows
CONTRAIL_L.FX & CONTRAIL_S.FX
notice the extension FX this is very important you should be able to find the original files on one of the install cd's
These file are locate inside of the effects folder
I also found this post that shows how to edit the contrails but it looks a little involved but you might want to look at it
