How do I wrap a curved line defined in a sketch around a curved surface?

I'm attempting to model a zig-zagging pipe around in a spiral something like this:

After defining a spiral surface, I would like to map a wavy line (series of alternating 90 degree curves) around it. Below is as far as I've been able to figure out:

I would appreciate any ideas?

I'd use the sketch wrap feature script https://cad.onshape.com/documents/0bb13c1b6ed6d4a6dd75cf99/v/e8fba514142b75a07c6f23b0/e/d12c4d024908a2d4e902fcfa from @konstantin_shiriazdanov.  I think that should work
