If you know the regiment/division you wish to replicate....a google image search should give you what you want
The 1st Cavalry Division were an exception, and had golden yellow piping instead of the Panzer pink.The Wehrmacht used coloured piping to show branch of service in the army - tank soldiers Pink. artillery red, infantry white, I've also seen yellow, bright green and blue which I think were signals, military police and no idea at the moment but I can look it up later if you like.

They look like the standard death's head patches to me. Or are you referring to the shoulder straps? Those are REALLY hard to make out.
