Heated handle full wrap, heated where?

[KerfWatcher]

Something I can't seem to get a clear answer on.....do factory heated full wrap handles have a heating element in the clutch side handle, or just use the conductivity of the handle to get heat out there? In other terms, are there any differences in a heated standard handle and a heated full wrap handle in the heating element / location aspect?

Thanks

Update: after friend checked for sure physically his saws . Nope he just got back and said his 372 full wrap heat is not go on the side.

He also checked the FW 371 G. Nope on it too.

Thanks. That is what I was pretty certain on, but wanted to confirm. I saw your original post and wanted to believe it, but glad your friend double checked.
I am looking to make some full wrap heated handles 550xp, etc but wasn't sure if the factory ones had the element on the clutch side.
